About this tool
A timezone converter lets you see the current time in several cities at once and translate a specific time across timezones. Scheduling a meeting with a global team, calling family overseas, or finding the local start time of a match or livestream no longer means doing "+/- hours" math in your head.
It relies on the standard timezone database and automatically handles Daylight Saving Time (DST) transitions — exactly where manual conversion goes wrong. Pick your cities and a time, and every location lines up at a glance. All conversion runs locally in your browser, with nothing uploaded.
How to use
- Add the cities or timezones you care about (e.g. Beijing, London, New York).
- Pick a reference time, or just use the current time.
- See that moment shown as the local time in every city you added.
- Drag or change the reference time and all cities update together, making it easy to find a slot that works for everyone.
When to use it
- Schedule cross-timezone video meetings or online collaboration.
- Find the local viewing time for an overseas launch, match or livestream.
- Agree on call times with clients or colleagues in other countries.
- Quickly compare the time difference between home and your destination before a trip.
FAQ
Does it handle Daylight Saving Time?
Yes. It uses the standard timezone rules to determine whether the target date is in DST and applies the right offset. That means the gap to a given city can differ between summer and winter — and that is handled correctly.
How far ahead is Beijing time from UTC?
All of China uses Beijing time (UTC+8), eight hours ahead of Coordinated Universal Time, with no DST, so it is fixed year-round. For example, 12:00 UTC is 20:00 in Beijing.
Does conversion need the internet? Is it private?
The conversion logic runs locally in your browser, and the cities and times you choose are not uploaded. Timezone and DST rules come from the database built into your browser or the tool, so everyday use needs no extra network requests.
