How the time zone converter works
Enter a time, choose the time zone it is in, and choose the zone you want it in. The tool finds the offset difference between the two zones and shifts the clock accordingly, flagging when the result lands on the previous or next day. It is the quick way to schedule calls and check arrival times across regions.
Working with UTC offsets
Each zone is shown as an offset from Coordinated Universal Time, such as UTC-7 for Mountain or UTC+9 for Tokyo. To convert, the tool subtracts the source offset and adds the destination offset. A few regions use half-hour offsets, like India at UTC+5:30, which the tool supports.
A note on daylight saving
Many regions shift their clocks for part of the year, which changes their offset. This converter uses the fixed offset you select, so during daylight saving periods pick the zone label that matches the current offset, or simply choose the offset that reflects the local time right now. Always double check important meetings.
Planning across zones
Use the day change and difference figures to avoid scheduling a call in the middle of someone night. The destination is ahead or behind label tells you at a glance which way the gap runs. For travel timing across zones, combine this with the travel time calculator.
