Frequently asked questions
How do I convert time between time zones?
Choose both zones and enter a time — the converted time plus the hour difference appear instantly.
Does it handle daylight saving?
Yes — offsets use the browser's IANA timezone database, which includes DST rules.
What does an offset like +05:30 mean?
How far the zone is from UTC: India is UTC+5:30, meaning it is 5.5 hours ahead of London winter time.
Why is the result an hour off sometimes?
Most likely daylight saving in one of the zones — check the offset shown next to each clock.
