Time Zone Converter for Dates & Times

Convert a specific date and time between two time zones for calls, events and remote collaboration.

Your files and tool inputs never leave this browser. This tool is free to use, with no account and no limit.

How to use this tool

  1. Enter the date and time in the starting location.
  2. Select the source and destination time zones.
  3. Check both the converted date and time, which update as you change the inputs.

Use a date, not just a fixed UTC offset

The difference between locations can change during daylight saving time. Named zones such as Europe/London are more useful than assuming a fixed offset all year. Browser time zone data determines the available rules. Times near clock changes can be ambiguous or nonexistent; verify these separately before scheduling.

Frequently asked questions

Does this handle daylight saving time?
Conversions use the time zone rules available in your browser. Clock-change hours can be ambiguous or nonexistent, so verify those times separately when arranging an event.
Why did the converted date change?
Locations can be on different calendar dates at the same instant. Check the full date in the output, especially when converting across midnight.
