How this handles daylight saving
Time zone conversion isn't a fixed offset — many places shift by an hour for part of the year, and not always on the same dates as each other. This uses your browser's own time zone database, the same one your operating system relies on, so daylight saving is handled automatically for whatever date you pick, not just today.
Common questions
Does this handle daylight saving time?
Yes — it uses your browser's own timezone database, which accounts for each region's current daylight saving rules automatically, including places that don't observe it at all.
What time zone is the date and time I enter in?
Your own — the browser's local time zone, detected automatically. Every other row shows what that same moment looks like elsewhere.
Can I compare more than three places at once?
Yes, add as many as you need with the Add time zone button, and remove any you don't need.
