Time Zone Converter

Time Zone Converter takes a date and time in one place and tells you what it is everywhere else you care about. Add as many zones as you need and they all update together, which is what makes it usable for arranging something across several countries rather than two.

Daylight saving is handled by the browser's own time zone database rather than by fixed offsets, which matters more than people expect. Countries change their clocks on different dates, some do not change at all, and a few have changed their rules in recent years. A converter using fixed offsets is wrong for several weeks each year; one using the real zone data is not.

Each zone shows the day as well as the time, because a conversion that crosses midnight changes the date, and a meeting scheduled on the wrong day is a more expensive mistake than one scheduled at the wrong hour.

• Convert between any two of hundreds of zones
• Add several destination zones at once
• Daylight saving handled from real zone data
• Shows the day as well as the time
• Offset from UTC and difference from the source
• Search zones by city name
• Set to the current moment in one click

The time zone converter is used by writers, developers, students, marketers and anyone else who needs the job done once without installing software. Common cases include:

• Scheduling a call across several countries
• Working out when a deadline falls in your own time
• Checking what time a live event starts locally
• Planning around a daylight saving change
• Converting a timestamp from a colleague in another country
