Frequently asked questions
How does daylight saving time work here?
The browser's Intl time zone data applies the correct offset for the selected date, including daylight saving time where it applies.
Why do some zones show the same time on some dates?
Zones that observe daylight saving time shift by an hour part of the year, so two zones can match in summer and differ by an hour in winter.
Can I convert a past or future date?
Yes. Enter any date and the converter applies the offset rules for that date.
What if my city is not listed?
Choose the nearest major zone in the same region, or pick a zone that shares the same standard offset and daylight saving rules.
