How to use

Convert across time zones in three steps

  1. Set the date and time you're starting from, and pick which time zone that time is in.
  2. Add one or more time zones you want to compare it against.
  3. Read the converted time for each zone, updated live as you change the source time.

Everything worth knowing before you dive in.

How it helps

Scheduling a call across regions usually means mental math with UTC offsets and remembering who observes daylight saving, easy to get wrong when a meeting matters. This tool uses your browser's built in time zone database, the same one that powers calendar apps, so conversions stay accurate even across daylight saving changes.

Built for real use

Set a source date, time, and time zone, then add as many comparison zones as the call needs, a common pattern for distributed teams spread across three or four regions. Each added zone updates instantly as the source time changes, so testing a few candidate meeting slots takes seconds.

Private by default

Because everything runs through the browser's native time zone data, there's no external API call and no risk of stale offset tables that some simpler converters rely on.

Pro tip

When scheduling a recurring meeting across regions, double check the converted time again close to the daylight saving change dates each region observes, since the offset between two zones can shift by an hour.

FAQ

Common questions

Does this account for daylight saving time automatically?

Yes, conversions use your browser's built in time zone database, which tracks daylight saving rules for each region automatically.

How many time zones can I compare at once?

There's no fixed limit, add as many as the meeting or schedule needs.

What time zone format is used?

Time zones are listed by region and city, such as America/New_York, matching the standard IANA time zone names used across most software.
