Frequently asked questions

What is a time zone converter?

A time zone converter changes a date and time from one location into the matching local time in other cities or IANA time zones.

How do I find a good meeting time across time zones?

Pick the host time, add each participant's time zone, and look for a window where every location falls inside normal working hours.

Does this converter handle daylight saving time?

Yes. The converter uses browser time-zone rules for the selected date, so daylight saving changes are reflected in the converted times.

What are IANA time zones?

IANA time zones are names like America/New_York or Europe/London. They are more reliable than fixed offsets because they include local daylight saving rules.

Does ChatSpark store the times I convert?

No. The calculation runs in your browser and does not send your selected time zones or meeting summary to ChatSpark.
