How to convert a time between time zones
Enter the date and time
Type the time you have, from a meeting invite or a deadline, and pick the time zone it belongs to. Now fills in the current time.
Add the zones you need
Search by city, region or offset, for example Istanbul, Pacific or +5:30. Your own time zone and UTC are there from the start.
Copy or share
Copy the list as text, or copy the link so others open the same conversion.
Why daylight saving makes conversions tricky
The gap between two cities changes during the year, because countries move their clocks on different dates and some never do. The converter reads each zone's rules from your browser, so the result is right for the exact date you enter, not just for today.
Times that don't exist or happen twice
When the clocks go forward, an hour is skipped: 02:30 on that night doesn't exist in Berlin, for example. When they go back, an hour happens twice. The converter tells you when this happens and which time it used.
Frequently asked questions
Where do the time zones come from?
From the time zone database built into your browser (the IANA database), the same one operating systems use. City names come from the zone names, such as Europe/Istanbul.
Is UTC the same as GMT?
For everyday use, yes. UTC is the reference that other zones are measured from. GMT is also the UK's winter time; in summer the UK uses BST, which is UTC+1.
What does the link contain?
Only the date, the time and the time zone names, written in the address. Nothing is stored on a server; whoever opens the link sees the same conversion.
