Scheduling across time zones is where meetings go to die: "3 PM your time or mine?" This planner kills the confusion. Pick a date and time in your zone, and instantly see that exact moment in 8 major zones β New York, London, Dubai, Karachi, Mumbai, Singapore, Sydney and UTC.
Choose the date, time and your zone, then press Show World Times. Each row shows the local day, date and time in that city, with your own zone badged. Daylight saving is handled automatically based on the date you pick β no manual UTC-offset maths.
Pro tips for global teams: aim for the overlap window (usually late afternoon Asia = morning Europe = early morning US East), rotate painful slots fairly instead of always punishing one region, and always send invites with the time zone attached ("15:00 GST") so nobody has to guess.
Planning something date-based too? Our Date Difference Calculator counts the days between any two dates.
Frequently Asked Questions
How does the conversion work?
Your date/time is converted to an exact UTC instant using your selected zone's rules (including daylight saving for that date), then formatted into each target zone. It's the same method operating systems use.
Why do some zones shift by an hour sometimes?
Daylight saving time: regions like New York, London and Sydney move clocks forward/back seasonally. The planner applies the correct offset for your chosen date automatically.
Which zones are included?
UTC, New York (Eastern), London, Dubai, Karachi, Mumbai (IST), Singapore and Sydney β covering the Americas, Europe, Middle East, South Asia and Australia.
Can I use this for flight times?
For rough planning, yes β but always confirm with the airline: flight schedules use local times and can be affected by schedule changes the planner can't know about.
