Frequently asked questions

Does the converter handle daylight saving time?

Yes. It uses the IANA timezone database, which encodes DST transitions for every region. Times near a switch boundary are computed correctly, including fractional offsets like India (+5:30) and Nepal (+5:45).

Why do some places not change for DST?

Many regions, including Japan, China, India, Iceland, and most of Africa, do not observe DST. Others, like Arizona in the US, opt out. The converter respects each region's rules automatically.

Can I save my common timezones?

Yes. Every city you add is saved automatically in your browser via local storage and will reappear the next time you open the tool. No account needed.

How do I plan a meeting across many timezones?

Open the Meeting Planner tab. The 24-hour UTC overlay highlights working hours (9 to 18 local) in every city. Cells outlined in green are the overlap. Use the day slider to shift the timeline forward or backward.

Is the data accurate for historical dates?

The IANA database goes back decades, so historical conversions are reliable for most modern dates. Very old dates (pre-1970) may be approximate as standard time was inconsistently observed.
