About This Tool

The Time Zone Converter helps you quickly convert times between any two timezones worldwide. It includes a visual meeting planner that shows business hour overlaps, making it easy to schedule calls and meetings across time zones. The tool covers major timezones from UTC-10 (Hawaii) to UTC+12 (New Zealand).

Daylight Saving Considerations

Daylight saving time shifts clocks forward by one hour in spring and back in fall. Not all countries observe DST, and those that do change on different dates. The offsets shown are standard time. During DST periods, US Eastern moves from UTC-5 to UTC-4, London moves from UTC+0 to UTC+1, and so on. Always verify the current offset if scheduling near DST transition dates (typically March and November in the Northern Hemisphere).

Scheduling Across Multiple Zones

When scheduling meetings across three or more timezones, look for the overlapping business hours window. US Pacific (UTC-8) and Central European (UTC+1) have a 9-hour gap, making the overlap window narrow: roughly 8-9 AM Pacific is 5-6 PM in Central Europe. Adding Asia-Pacific participants may require rotating meeting times so the inconvenience is shared fairly.

Frequently Asked Questions

How does daylight saving affect the conversion?
DST shifts the UTC offset by 1 hour for participating regions. This tool shows standard time offsets. During DST, add 1 hour to the offset for regions that observe it. US, Canada, EU, and parts of Australia observe DST. Japan, China, India, and most of Africa do not.
What is UTC?
UTC (Coordinated Universal Time) is the global time standard. It does not change with daylight saving. All time zones are defined as offsets from UTC. UTC+0 is equivalent to GMT (Greenwich Mean Time) for practical purposes.
How do I handle half-hour timezones?
India (UTC+5:30), Nepal (UTC+5:45), and parts of Australia (UTC+9:30) use fractional offsets. This tool includes India at +5.5. For others, manually adjust the converted time by the fractional amount.
What is the International Date Line?
The International Date Line runs roughly along 180 degrees longitude in the Pacific Ocean. Crossing it westward adds a day; crossing eastward subtracts a day. This is why there can be a +1 day or -1 day note on your conversion.
Best time for US-Europe meetings?
The optimal window is typically 8-10 AM US Eastern, which is 2-4 PM in Central Europe. For US Pacific teams, 7-9 AM Pacific works but that is already 4-6 PM in Central Europe, near end of business day.
