How to use Time Zone Converter
Convert a date and time from one time zone into as many others as you need, with daylight saving shown for each place. A meeting planner highlights hours that fall within everyone’s working day. It uses your browser’s time zone data and works offline.

Under Time to convert, set the Date and Time or click Now, and choose the source Time zone.
- 2
Use Add a time zone to search by city, country or abbreviation, such as Beijing, PST or CET.
- 3
Read each zone’s local time, day difference and Summer time or Standard time label; click Use as source to convert from that zone instead.
- 4
In the Meeting planner, click a column to pick an hour when everyone is within working hours.
- 5
Set 24-hour clock and Working hours under Display, then use Copy summary or Copy link to share the result.
Frequently asked questions
Does it handle daylight saving time?
Yes. Offsets come from your browser’s built-in time zone database for the exact date you enter, so past and future dates are correct. Each zone shows whether summer time is in effect and when clocks next change.
What if the time does not exist or happens twice?
When clocks jump forward, a time in the gap is moved past it. When clocks fall back, the repeated hour uses its first occurrence (summer time). A note explains it in both cases.
I typed CST but got Chicago. How do I find China time?
Abbreviations are ambiguous, and CST matches US Central Time. For China Standard Time, search Beijing or Shanghai; each search result shows its UTC offset so you can check before picking.
How do I share a meeting time with others?
Copy link creates a URL with the date, time, source zone and your other zones, so the page opens with the same conversion. Copy summary copies the times as plain text.
Are my zones remembered?
Yes. Your list of zones, the 24-hour setting and working hours are saved in this browser and restored next time. Nothing is sent to a server.
