ZoneMeets is a free time zone converter and meeting planner. Pin cities side by side, drag a time slider to see which hours fall inside business time for everyone, check upcoming public holidays for each country, and add the meeting to your calendar. It uses the IANA time zone database, so daylight saving changes are always applied correctly. This site needs JavaScript to run the interactive tools.
