Time Zone Converter

Frequently asked questions

How many time zones can I compare at once?

Add as many as you need — each one you add shows its own converted local time, UTC offset, and whether it falls on a different calendar day than your source time.

Does it account for daylight saving time?

Yes — conversions use your device's time zone database (IANA tz data), which includes each region's current daylight saving rules, so offsets are correct for the specific date you pick, not just a fixed UTC offset.

Why does the converted time sometimes land on a different day?

Large offsets between time zones can push the equivalent local time past midnight in either direction. The tool flags this so you don't miss that a meeting lands "tomorrow" or "yesterday" for someone else.

Is my chosen date and time sent to a server?

No. All conversion happens locally using your browser's built-in time zone data — nothing is sent or stored, and no account is needed.

Do I need to install anything or sign up?

No. It runs entirely in your browser — no software install, no account, no email required.
