Frequently asked questions
Does it handle daylight saving?
Yes. The planner uses the browser's IANA timezone database, which tracks DST for any city listed.
Can I add an arbitrary UTC offset?
Yes. Type a number with a sign, for example "+5" or "-3.5", and the planner interprets it as hours from UTC.
