Convert Time Between Time Zones
Timezone conversion is most reliable when you choose named locations and a specific date instead of applying a remembered UTC offset.
Use a location and date
Select the source location, destination location, and actual calendar date for the event. Named timezones apply the correct offset rules for that point in the year.
Watch for date changes
A converted time can move to the previous or following calendar day. Include the date whenever you share travel arrivals, launch windows, or international deadlines.
Verify recurring schedules
Repeat the conversion for dates near daylight saving transitions. Two locations may change clocks on different weekends, temporarily shifting their usual time difference.
Frequently Asked Questions
Why can the timezone difference change during the year?
Locations can start or end daylight saving time on different dates.
Should I use a city or a fixed UTC offset?
Use a city when possible because it preserves local daylight saving rules.
