FAQ
What is the UTC offset for a timezone like Asia/Kolkata?
+05:30 right now. Search any city or region on this page and its current offset appears instantly, read from your device's own timezone data — so daylight-saving shifts are always applied correctly for today's date.
Why does the offset change through the year?
Many zones observe daylight saving, shifting their offset by an hour for part of the year. Because this list reads the current offset from your device, it shows the right value for today rather than a fixed number.
Is anything uploaded?
No — the zones come from your browser's built-in Intl timezone data and are searched locally; it works offline.
How many timezones are there?
Several hundred IANA zones, named by region and city (Asia/Kolkata, Europe/London). The full list your device supports is shown.
Limits
