About World Date & Time Formats
The World Date & Time Formats tool shows how dates and times are actually written around the world. Search for any country or language, add it to the comparison, and instantly see its short, long and full date forms, its time notation and whether it uses a 12-hour or 24-hour clock — all generated live from your browser’s own locale data.
The same string of digits can mean two different days: 03/04/2025 is March 4 in the United States and April 3 in most of Europe. Developers localizing an app, designers building date pickers and anyone writing for an international audience use this comparison to see each locale’s day–month–year order at a glance and avoid that ambiguity.
Your own locale is detected from your browser settings and marked as “You”, so you always have a familiar baseline to compare against. Each locale card also shows the current local time next to UTC, and every formatted value can be copied to the clipboard with one click. Nothing is sent to the server.
How to use World Date & Time Formats
- Type a country or language into the search box — for example Japan, German or pt-BR — and click a result to add it.
- Add more locales the same way, browse the regional groups (Americas, Europe, Asia and so on), or click “Add popular locales” to fill the comparison in one go.
- Compare the short, long and full date rows side by side, and check each locale’s date-order badge (Day–Month–Year, Month–Day–Year or Year–Month–Day).
- Toggle between the 12-hour and 24-hour clock to see how times are written in each locale.
- Click any formatted value to copy it, and remove or clear locales when you are done.
