24-Hour Time Around the World
Updated June 13, 2026
Most of the world uses the 24-hour clock for written schedules, timetables, and official communication. The main exception is the English-speaking world — the US, Canada, Australia, and the UK — where the 12-hour clock still dominates daily life. Here is a breakdown by region.
Direct answer
If you are in Europe, Latin America, Asia, or Africa, expect written times in 24-hour format — 18:30 not 6:30 PM. If you are in the US, Canada, Australia, or the Philippines, expect 12-hour time with AM/PM. When in doubt, check the context: a train ticket showing 18:30 means evening; a store sign showing 6:30 means morning or evening depending on context.
Quick reference by region
| Region | Dominant format | Notes |
|---|---|---|
| Europe | 24-hour | Written schedules use 24-hour. Spoken language often converts to 12-hour. |
| Latin America | Mixed | Written 24-hour is common. Spoken 12-hour with time-of-day words. |
| Middle East | Mixed | Varies by country. 12-hour is common in Gulf states for daily life. |
| East Asia | Mixed | Japan uses 24-hour for schedules. China often uses 12-hour in daily life. |
| South Asia | 12-hour | India, Pakistan, Bangladesh use 12-hour for most purposes. |
| Southeast Asia | 12-hour | Philippines, Malaysia, Indonesia primarily use 12-hour. |
| Africa | Mixed | Former British colonies lean 12-hour. Francophone Africa uses 24-hour. |
| Oceania | 12-hour | Australia and NZ use 12-hour for daily life. 24-hour in some official contexts. |
The pattern is simpler than it looks
Here is the rough rule: countries that were part of the British Empire tend to use the 12-hour clock in everyday life. Countries that were not — or that deliberately standardized their systems in the 20th century — tend to use the 24-hour clock for written communication.
That means the US, Canada, Australia, India, and the Philippines share the 12-hour habit. France, Germany, Spain, Italy, Brazil, and most of continental Europe and Latin America use 24-hour for schedules, even though people speak in 12-hour terms.
This split is not just about history. It is also about infrastructure. Countries that built national railway systems in the late 1800s and early 1900s had to pick a time format for timetables. Most chose 24-hour to avoid confusion. The US and Britain, having built their railways earlier, already had 12-hour schedules and saw no reason to change.
Country-by-country examples
France
Strict 24-hour in writing. A store sign says 14h-18h. But a person says "deux heures" (two o'clock), not "quatorze heures."
Germany
24-hour everywhere in writing. Even informal text messages often use 24-hour. Spoken German sometimes uses 24-hour phrasing too.
Brazil
Written schedules and business hours use 24-hour. Spoken Portuguese drops to 12-hour with words like "da tarde" (in the afternoon).
Japan
Train schedules, TV listings, and official documents use 24-hour. Casual conversation uses 12-hour with "gozen" (AM) and "gogo" (PM).
Canada
English-speaking Canada uses 12-hour. Quebec, influenced by France, uses 24-hour more often in writing. The country is genuinely split.
United Kingdom
Mixed. BBC schedules use 24-hour. Rail timetables use 24-hour. But most people use 12-hour in daily conversation and informal writing.
What this means for travelers
If you are traveling from the US to almost anywhere else, get comfortable reading 24-hour times. You will see them on:
- Train and bus tickets
- Flight confirmations from non-US airlines
- Hotel check-in and check-out signs
- Museum and attraction opening hours
- Restaurant reservation confirmations
- Concert and event tickets
The main thing to remember: if you see a time above 12:59, subtract 12 to get the PM equivalent. 14:00 is 2 PM. 19:30 is 7:30 PM. 22:00 is 10 PM. After a day or two of seeing these, the conversion becomes automatic.
