Which time zones are listed?

The tool uses IANA zones such as Europe/London so daylight saving changes automatically follow regional rules.

Does it handle half-hour offsets?

Yes. Regions like India (UTC+5:30) render with the correct fractional offset.

What about historical DST?

Conversions use the zone rules bundled with your browser; edge historical dates may differ from archival government tables.

Can I paste a meeting invite time?

Enter the local time shown on the invite and pick the invite's stated zone to map elsewhere.

No server round-trip — calculation is local after load.

Why is my result off by an hour?

Check whether the source city observes DST on that calendar date and pick the exact zone name, not a fuzzy abbreviation.

Can I compare more than two zones?

Run sequential conversions or pair with World Clock pages for grid views.

Yes. Touch-friendly pickers work on phones in landscape or portrait.
