How to Convert Time Zones
The Time Zone Converter helps you convert any time between world time zones. Essential for scheduling international calls, planning travel, coordinating remote teams, or knowing what time it is anywhere in the world.
Understanding Time Zones
The world is divided into 24 standard time zones, each roughly 15 degrees of longitude apart. UTC (Coordinated Universal Time) is the reference point. Eastern Time is UTC-5 (or UTC-4 during daylight saving).
Common Time Zone Conversions
- US Eastern to Pacific: Subtract 3 hours
- New York to London: Add 5 hours (or 4 during DST)
- Los Angeles to Tokyo: Add 17 hours
- Sydney to New York: Subtract 15-16 hours
Daylight Saving Time
Many regions observe daylight saving time (DST), shifting clocks forward in spring and back in fall. Our converter accounts for DST automatically based on current dates.
