The meeting scheduler is perfect for coordinating with remote teams. I pick a time in my zone and instantly see it in New York, London and Tokyo. Saved me from many scheduling mistakes.

The live world clock showing all cities at once is brilliant. I have it open on my second monitor all day. The DST-aware conversions are spot on — crucial for spring/autumn scheduling.

Yes. All conversions use the browser's built-in Intl.DateTimeFormat API which automatically applies the correct DST offsets for each zone based on the actual date. Selecting different dates in the Meeting Scheduler will correctly reflect winter/summer time changes.
What is UTC and why is it used as a reference?+
UTC (Coordinated Universal Time) is the global time standard that all other time zones are defined relative to. It replaced GMT as the international standard and has no daylight saving offset. UTC+0 = London winter time (GMT). All time zone offsets are expressed as UTC±N hours.
How many time zones are there in the world?+
There are 38 distinct UTC offsets ranging from UTC−12:00 to UTC+14:00. Some countries use half-hour or quarter-hour offsets (e.g. India UTC+5:30, Nepal UTC+5:45, Australia's central zone UTC+9:30). The IANA tz database — which this tool uses — contains over 500 named zones to account for historical DST differences.
What is the best time to schedule a meeting between New York and London?+
New York is UTC−5 (EST) or UTC−4 (EDT). London is UTC+0 (GMT) or UTC+1 (BST). The overlap window for standard business hours (9am–6pm both sides) is typically 2pm–6pm London = 9am–1pm New York (in winter). Use the Meeting Scheduler above to check exact times for any date.
Is the data private?+
Yes. All conversion uses the browser's built-in Intl.DateTimeFormat and Date APIs. No time values or zone data are sent to any external server.
