Frequently Asked Questions

Can I get the current time in a city without knowing its IANA code?

Yes. `current_time` accepts city names directly, so you can ask for Tokyo, New York, or similar locations without looking up a timezone ID first.

How do I convert time between two places?

Use `convert_time` with a source timezone and a destination timezone. If you leave out `datetime`, it converts the current time instead.

Can I check DST and UTC offset details?

Yes. `timezone_info` shows the current UTC offset, standard offset, DST status, and the next transition dates for that timezone.

How do I browse valid timezone names?

Use `list_timezones` to browse IANA timezone identifiers by region, such as Europe or America.
