Executive Summary
A widespread habit, often attributed to Canadians but found across many regions and households, expresses the distance between two places as a duration rather than a length. A town is “three hours away” rather than “290 kilometers away.” The habit is neither imprecise nor provincial. It reflects a long tradition in human geography, transportation planning, and ancient practice, including the practice recorded in Scripture, which holds that distance matters because of what it costs a traveler to cross it. This paper argues that time-based distance is a measure of friction, or the effort, exposure, and opportunity a journey consumes. It examines why the practice arises, where it is most entrenched, what scholarship has found about it, and what it reveals about the true determinants of separation between two points. It concludes that physical length is the least informative measure of distance for human purposes, and that the relationship between places is set by access, cost, and the willingness of people to make the journey.
1. Introduction: A Habit That Is Not Merely Canadian
Popular commentary often treats the Canadian tendency to describe distance in hours as a national quirk born of vast territory and sparse settlement. The explanation is partly right. In a country where a provincial capital may sit many hours from the next significant city, and where winter conditions can double a journey’s length, a figure in kilometers says little about what a trip will demand. Yet the practice is far broader than Canada. It appears in the American South and West, in rural Australia, in Alpine trail signage, in commuter culture in large metropolitan regions, and in countless family conversations where “how far is it?” is answered “about forty minutes.” [1]
The persistence of the habit across cultures with very different geographies suggests that it rests on something more basic than national temperament. It rests on the recognition that the distance which matters to a person is not the length of a line on a map but the portion of a day, a budget, or a life that must be given up to reach a destination.
2. The Ancient Pedigree of Time-Distance
Measuring distance by travel time is far older than the odometer. Before standardized units and reliable surveying, the most dependable gauge of separation was how long a journey took on foot or by beast.
2.1 The Biblical Record
Scripture repeatedly expresses distance as time. Laban set “three days’ journey betwixt himself and Jacob” (Genesis 30:36, KJV). Moses asked Pharaoh to let Israel “go, we beseech thee, three days’ journey into the wilderness” (Exodus 3:18). Elijah “went a day’s journey into the wilderness” before sitting under the juniper tree (1 Kings 19:4). Nineveh is described as “an exceeding great city of three days’ journey” (Jonah 3:3). Joseph and Mary traveled “a day’s journey” before realizing the young Jesus Christ was not among their company (Luke 2:44). After the ascension, the disciples returned from Olivet, which is described as “a sabbath day’s journey” from Jerusalem (Acts 1:12). [2]
These references are not vague. For an audience that traveled on foot, “a day’s journey” conveyed a concrete quantity of effort, provisioning, and exposure. The sabbath day’s journey in particular shows that a time-and-effort measure could carry legal and moral weight within the community that used it. [3]
The most instructive biblical example is Deuteronomy 1:2: “There are eleven days’ journey from Horeb by the way of mount Seir unto Kadeshbarnea.” The verse stands at the opening of a book that recounts forty years of wandering. The geographic distance never changed; eleven days remained eleven days. What changed was the time the people actually spent, a span stretched by unbelief and disobedience rather than by terrain. The passage separates the time a route requires from the time a people take, and it locates the difference in conduct rather than in geography. [4]
2.2 Classical and Pre-Modern Practice
Other ancient systems show the same logic. Herodotus described the Persian Royal Road from Sardis to Susa by stages and days of travel, computing roughly three months for the full journey. [5] The Persian parasang, though later given a fixed length, appears to have originated as a distance a person could cover on foot in a fixed span of time. The English and French league was commonly understood as the distance a person could walk in about an hour. The Roman mile itself derived from a count of paces, a body-based measure that tied distance to the walking human rather than to an abstract standard. [6]
The pattern continues into modern trail practice. Naismith’s rule, formulated for Scottish hill walkers in 1892, estimates walking time from horizontal distance plus an allowance for ascent, which openly treats the hill as adding “distance” in the form of time. [7] Swiss hiking signs today commonly list destinations in hours and minutes rather than kilometers, because a short trail with steep ascent can take longer than a long trail on level ground. [8]
3. The Geographic Principle: Distance as Friction
3.1 From Absolute to Relative Distance
Geographers distinguish between absolute distance, the measured length between two points in a fixed coordinate system, and relative distance, which measures separation in terms of time, cost, effort, or perception. [9] Absolute distance remains constant, while relative distance changes with technology, infrastructure, season, and circumstance. Time-distance is the most familiar form of relative distance, because time is the one cost every traveler pays and the one resource no traveler can replenish.
Tobler’s often-cited “first law of geography,” which holds that near things are more related than distant things, depends on what “near” means. [10] In practice, the relationships Tobler described are governed less by kilometers than by the ease of movement between places. Two towns separated by a mountain range may be closer in kilometers than two towns on opposite ends of a highway, yet the latter pair will trade, intermarry, and share institutions more readily.
3.2 The Friction of Distance
The concept of “friction of distance” captures the idea that interaction declines as the cost of movement increases. [11] That cost has several components:
- Time, the hours consumed in transit;
- Money, the fares, fuel, and lodging required;
- Effort and fatigue, the bodily and mental toll of the trip;
- Risk, including weather, road hazards, and the uncertainty of arrival;
- Opportunity cost, the other uses of the same time that must be forgone.
Time is the most convenient single proxy for this bundle, because it correlates with most of the other costs and because people experience it directly. When a family says a city is “two hours away,” the figure communicates not only duration but also how early to leave, whether to pack a meal, whether the trip can be made and returned from in a day, and whether children will tolerate it.
3.3 Accessibility over Proximity
Transportation planners formalized this insight in the concept of accessibility. Hansen defined accessibility as the potential for interaction with opportunities, weighted by the difficulty of reaching them. [12] Under this view, a location’s value depends on how many jobs, services, relatives, or places of worship can be reached within a given travel time. Stouffer’s earlier theory of “intervening opportunities” made a related claim: the number of trips to a destination depends less on raw distance than on how many comparable opportunities lie in between. [13] Both approaches treat distance as an effect of the network and the opportunities it connects rather than as a fixed property of the landscape.
4. Time-Space Convergence and the Shrinking World
4.1 Janelle’s Convergence
Janelle introduced the concept of time-space convergence to describe the decline in travel time between places as transportation improves. [14] His classic illustration traced how the journey between two British cities fell from days by stagecoach to hours by rail and then to less by road and air. In absolute terms, the cities never moved. In the terms that governed commerce, correspondence, and family life, they drew dramatically closer.
Convergence is uneven. Places on main lines, near airports, or along interstate highways converge rapidly, while places off the network may remain as “far” as they were a century ago or even grow more remote as services are withdrawn. A rural town that loses its rail line, bus service, or regional airport experiences time-space divergence. [15] This unevenness explains why time-based distance feels so natural in regions such as Canada: the network is thin, its links are long, and the difference between being on and off it is stark.
4.2 Compression and Its Consequences
Harvey extended the idea into time-space compression, arguing that modern economic life speeds up turnover and shrinks the felt dimensions of the world, with disorienting effects on how people relate to place. [16] Whatever one makes of Harvey’s broader framework, the observation holds that once distance is measured in time, any improvement in speed restructures social and economic geography. Suburbs, commuter belts, and megaregions are products of this restructuring.
5. The Daily Travel Budget: Why Time Sets the Boundaries of Ordinary Life
One of the most striking findings in transportation research is the apparent stability of the amount of time people devote to daily travel. Zahavi observed that household travel time budgets remained broadly consistent across very different cities and income levels. [17] Marchetti later argued that people across many societies and periods have averaged about an hour of travel per day, a figure now often called “Marchetti’s constant.” [18] Under this view, improvements in speed do not reduce time spent traveling; they extend the area a person covers in the same time.
The constancy has been debated. Mokhtarian and Chen found substantial variation once individual and household characteristics were accounted for, and cautioned against treating any fixed budget as a law. [19] A later review by Ahmed and Stopher concluded that average daily travel time tends to cluster around an hour, with meaningful variation across contexts. [20] Even with these qualifications, the general pattern supports the family habit of measuring distance in time: people organize their lives around a tolerable span of travel, and the places that fall within that span constitute their working world.
This is why the phrase “it’s only twenty minutes” carries real meaning. It places a destination within the ordinary daily range. “It’s three hours” marks a place outside that range, a place reached by planning rather than routine.
6. Cognitive Distance: How People Actually Perceive Separation
Research in behavioral geography shows that people’s sense of distance departs systematically from measured length. [21] Routes with many turns, intersections, or landmarks tend to be judged longer than straight, featureless routes of equal length. Trips toward a city center are often perceived differently from trips away from it. Familiar routes tend to feel shorter than unfamiliar ones. [22]
Montello’s review of distance cognition identified several bases on which people judge distance, including the number of features passed, the effort expended, and the time elapsed. [23] Time is among the most accessible of these cues, because people carry clocks and remember durations. A traveler may not know whether a route is 140 or 180 kilometers long, but remembers that it took “about two hours.” Time-based description thus aligns the language of distance with the way distance is actually stored and recalled.
7. Why Time-Distance Flourishes in Certain Places
Time-based distance is used everywhere, but some conditions make it dominant:
- Low-density, large-scale territory. Where settlements are widely spaced, as in Canada, the interior American West, and Australia, kilometers convey little without knowledge of road quality and speed.
- Automobile dependence. Where nearly all travel is by private car, door-to-door driving time becomes the common currency of distance.
- Variable conditions. Seasonal weather, mountain passes, ferry schedules, and border crossings make travel time unpredictable, so people report the time that matters rather than a length that does not.
- Congestion. In large metropolitan regions, a distance of fifteen kilometers may take fifteen minutes at night and seventy-five at rush hour, so residents speak in time and specify the hour of travel.
- Family and community networks. Where relatives and congregations are spread across a region, the relevant question is whether a visit can be made within a day, a weekend, or a holiday, and time answers that directly.
The fact that the habit appears in family practice far from Canada shows that it arises wherever these conditions combine.
8. What Time-Distance Reveals About What Truly Matters
8.1 Distance Is a Relationship, Not a Property
Time-based distance shows that separation between two places is a relationship between those places, the people traveling, and the means available to them. A town is not “far” in itself. It is far for someone, by some means, at some time. A destination three hours away by car may be a full day away for someone without a car, and unreachable for someone who cannot afford the trip or who lacks the health to make it. The measured length is the same for all; the real distance differs for each.
8.2 Cost and Willingness Determine Nearness
If distance is a cost, then nearness depends on both the cost of a trip and the value placed on the destination. People routinely travel great time-distances to see those they love, to attend worship, or to fulfill obligations, while neglecting places that are close by in every measurable sense. The road to a parent’s home may be “only four hours” in one family’s reckoning and “too far” in another’s. The difference lies not in the road but in the relationship.
8.3 The Biblical Lesson of Kadesh-barnea
The account in Deuteronomy 1:2 offers the clearest statement of this principle. The route from Horeb to Kadesh-barnea was an eleven-day journey. Israel’s actual passage stretched across forty years, not because the land grew wider but because the people refused to enter when they arrived (Numbers 14). The distance that mattered was set by obedience and trust, not by the length of the road. [24] Time-distance, in this light, is a measure of more than speed and terrain. It reflects the condition of the traveler.
The parable of the Good Samaritan makes a related point about proximity. When asked “who is my neighbour?” (Luke 10:29), Jesus Christ answered with a story in which the priest and the Levite were physically near the wounded man and passed by, while the Samaritan, a stranger by origin, “came where he was” and acted (Luke 10:33). The neighbor was the one who closed the distance. Physical proximity alone did not make someone near. [25]
8.4 The Limits of Time as a Measure
Time-distance is a better guide than length, but it is not complete. It obscures differences in monetary cost, comfort, and danger. It favors those with cars and flexible schedules. It can make well-connected places seem close while hiding the isolation of those left off the network. A full account of distance must also consider cost, access, and the will to travel. Still, time captures more of what matters to a traveler than any measure of length, and the habit of reckoning in hours is a sound instinct rather than a lapse in precision.
9. Conclusion
The practice of measuring distance in time, so often treated as a Canadian peculiarity, belongs to a much older and wider human tradition. It appears in the journeys of Scripture, in the leagues and parasangs of the ancient world, on Alpine trail signs, and at kitchen tables wherever families plan visits. Geographic scholarship confirms what the habit implies: the distance that governs human life is relative, shaped by the friction of movement, the structure of transportation networks, the limits of daily travel time, and the way people perceive and remember their routes.
What truly determines the distance between two points, then, is not the straight line connecting them but the cost of crossing between them and the willingness of people to pay it. Time is the clearest single expression of that cost. And as the eleven-day road that took forty years shows, the time a journey takes is finally governed as much by the traveler as by the terrain.

[3] The sabbath day’s journey was a customary limit on travel on the seventh day. Acts 1:12 uses it as a distance marker without explanation, indicating that first-century readers understood it as a recognized measure.
[4] The forty-year duration is stated in Numbers 14:33–34, where the period is tied to the forty days of spying out the land, “each day for a year.” The juxtaposition with Deuteronomy 1:2 sets the required travel time against the time actually spent.
[5] Herodotus, Histories 5.52–54, describes the stations along the Royal Road and calculates the journey at a rate of 150 stades per day.
[6] The Roman mille passus, “a thousand paces,” counted double steps of a marching soldier. Pre-modern units of this kind tied measurement to the human body and its movement.
[7] Naismith’s original rule allowed one hour for every three miles of horizontal distance plus an additional hour for every 2,000 feet of ascent. Later refinements adjusted the figures, but the principle of converting terrain into time remains.
[8] Tobler’s hiking function offers a mathematical formulation of the same idea, estimating walking speed as a function of slope.

[11] The friction of distance underlies gravity models of spatial interaction and the distance-decay functions widely used in geography and transportation planning. Ullman (1956) identified complementarity, intervening opportunity, and transferability as the bases of spatial interaction.
[12] Hansen (1959) defined accessibility in terms of the spatial distribution of activities adjusted for the ability and desire of people to overcome spatial separation.
[13] Stouffer (1940) proposed that the number of persons moving a given distance is proportional to the opportunities at that distance and inversely proportional to the intervening opportunities.
[14] Janelle (1968, 1969) developed time-space convergence as a measurable rate of decline in travel time between places.
[15] Divergence occurs when travel time between places increases, as when services are withdrawn or congestion grows faster than capacity.
[16] Harvey (1989) frames compression within a broader account of economic change; the geographic observation about shrinking felt distance can be accepted independently of his larger argument.
[17] Zahavi’s work for the World Bank and the U.S. Department of Transportation in the 1970s established the travel time budget as a research topic.
[18] Marchetti (1994) drew on historical and cross-cultural data to argue for a roughly constant daily travel time of about one hour.
[19] Mokhtarian and Chen (2004) reviewed the evidence and concluded that travel time expenditures vary systematically with individual, household, and environmental characteristics.
[20] Ahmed and Stopher (2014) reviewed travel time budget studies and found averages clustering around 60 to 80 minutes per day.
[21] Golledge and Stimson (1997) survey the field of spatial behavior and cognition.
[22] These effects are associated with the number of route segments, the density of environmental features, and familiarity with the route.
[23] Montello (1997) organized the bases of distance judgment into categories including number of features, travel time, and travel effort.
[24] The narrative of the refusal at Kadesh-barnea is in Numbers 13–14; Moses recounts it in Deuteronomy 1:19–46.
