Timezone Converter: Plan Across Time Zones
Convert times between any two time zones worldwide. Essential for scheduling international meetings, planning travel, and communicating across continents.
Formula
Target Time = Source Time + (Target Offset − Source Offset). The calculator uses standard time zone data to find the exact time difference and handles daylight saving time automatically for supported zones.
Worked example
3:00 PM in London (GMT) to Tokyo (JST): Tokyo is 9 hours ahead, so 3:00 PM GMT = 12:00 AM midnight JST the next day.
Practical guidance
Daylight saving time complexities
Not all regions observe daylight saving time, and those that do change on different dates. The calculator uses current rules, but future dates near transition periods may need verification. Always double-check critical meeting times.
Best times for global meetings
Finding a time that works for participants across multiple zones is challenging. Midday UTC (12:00) often works for Europe afternoon and Asia evening. Early morning UTC (08:00) suits Europe morning and Americas early hours. Use the converter to test options before sending invites.
