Compare the time in multiple cities at once for any date, with daylight saving handled automatically. Covers 190+ countries and every major capital city.
How to compare time zones and plan a meeting
Your own city is detected automatically as the reference, with the current date and time filled in. Search for a city or country and select Add city to compare its local time for the same moment.
Change the reference date and time to plan a future meeting, or press Now to jump back to the current moment. Every other city updates instantly, including the correct daylight saving offset for that specific date, not just today's offset.
Each city shows whether that time falls in a typical 9:00-17:00 business day on weekdays. Use Use as reference on any city to view the same moment from that city's local time instead, without re-entering the date.

Your local city is added automatically as the reference. Search for another city and select Add city; its local time for the same moment appears below the reference, and you can add as many cities as you need.
Change the reference date and time fields, or use the calendar button to pick a date. Every added city recalculates its local time for that exact moment, including whether daylight saving time applies on that date.
Yes. Each city's local time is calculated from its real time zone rules for the date you chose, so daylight saving changes are applied automatically and correctly, even for a date where only some of the cities involved observe daylight saving. A DST badge appears next to the UTC offset whenever that city is currently in daylight saving time.
The capital city of essentially every country, plus the capital of every individual US state, since several states keep their own time zone rules (Arizona and Hawaii, for example, do not observe daylight saving). Countries that span several time zones, such as Russia, the United States, Canada, Australia, France (including its overseas territories), Brazil, Mexico, Indonesia, Kiribati and Chile, also have a representative city added for each of their zones. On top of that, 30 of the world's largest cities that are not national capitals are included too (for example Shanghai, São Paulo, Mumbai, Istanbul and Lagos), since those are some of the most commonly searched cities of all.
UTC+14 is the earliest time zone and includes Kiritimati (Christmas Island) in Kiribati. The latest inhabited time zone is UTC-11, used by Niue and American Samoa; the uninhabited UTC-12 zone at Baker and Howland Islands is the technical extreme. Kiritimati and Niue can show dates and times up to 25 hours apart on the clock. Both places are in this calculator's city list, so you can compare them directly.
It shows whether the calculated local time for that city falls between 9:00 and 17:00 on a weekday, a quick way to see which cities in your comparison are inside a typical working day at the chosen moment.
Switching the reference keeps the same underlying moment in time and simply redisplays it using the new city's local date and time, so results for every other city stay the same; only the reference fields themselves update.
