Time zone converter — compare cities at a glance
Compare the current time across cities before calling or messaging. Each row includes the local date, weekday and UTC offset, so you can see when it is already tomorrow elsewhere.

How to use
- Choose a reference zone. It appears first in the list. The results follow the live clock.
- Add the places you need. Use Add a zone to select cities, and Remove to shorten the list.
- Check the date as well as the time. An offset of UTC+05:30 means 5 hours 30 minutes ahead of UTC: when UTC is 12:00, that zone reads 17:30 on the same date.
Questions
Can I check a future meeting time here?
The current page stays in live-clock mode and its custom date-time field is disabled. Use these rows for current-time comparisons. For a future meeting, use a calendar that accepts the event date and named time zone.
Does the offset change with daylight saving?
Where a zone observes daylight saving, the browser supplies the offset for the current instant. A time difference that works today may change on another date, particularly when cities change clocks on different weekends.
Should I share an abbreviation such as EST?
A city-based zone name, date and time is clearer. Abbreviations can be ambiguous, and the browser may display a GMT offset instead. Include the numeric offset shown when describing the current time.
