Preguntas frecuentes

Quick answers.

Which timezones are supported?

All IANA zones — over 400 of them, including legacy aliases. Same data set used by every modern operating system.

Does it handle daylight saving?

Yes. We use your browser's IANA timezone database, which knows DST start/end dates for every zone past and future.

What's the difference between EST and EDT?

EST is Eastern Standard Time (UTC-5, winter). EDT is Eastern Daylight Time (UTC-4, summer). Use 'America/New_York' to get the right one automatically.

Why does my conversion differ from another tool by 1 hour?

Almost always a DST mismatch. Check that both tools use the same date — the offset can change overnight when DST starts or ends.

Is the timezone converter free?

Yes — free, no signup, no ads, runs in your browser.
