Frequently Asked Questions
Does this account for daylight saving time?
Yes, it uses each timezone's actual rules for the specific date you select, so the offset automatically adjusts correctly across daylight saving transitions.
Why do some regions show unusual offsets like +5:30?
Not every timezone uses a whole-hour offset - India Standard Time (UTC+5:30) and Nepal (UTC+5:45) are well-known examples of half-hour and quarter-hour offsets.
Is my data sent to a server?
No. All conversion happens entirely in your browser using its built-in timezone database.
How accurate is the browser's timezone data?
Modern browsers include the IANA Time Zone Database, the same authoritative source used by most operating systems and programming languages, and it's updated regularly.
Can I add a timezone that isn't listed?
This tool shows a curated list of commonly needed timezones. For a timezone not listed, you can calculate the offset manually using a region with a known, identical offset.
