Time Zone Converter
A time zone is just a fixed offset from UTC, so converting a time between two zones is a single addition: take the time you have, add the difference between the two offsets, and read the result off a 24-hour clock. When that addition carries past midnight or back before it, the clock wraps around and the date moves too โ which is why the day shift is reported separately instead of being hidden inside the time.
How it works
Frequently asked questions
Why does the converted time sometimes show a different day?
Clocks wrap at midnight. If you convert 23:00 from UTC to UTC+2 the result is 01:00, but it is 01:00 the next day โ that is the day shift. If you convert 02:00 the other way you land on 00:00 the previous day, and the shift is -1.
Does this account for daylight saving time?
Not automatically. Daylight saving is a political decision that changes on short notice, so this converter works with fixed UTC offsets. During summer, pick the offset your zone is actually using at that moment โ for example UTC+2 instead of UTC+1 for most of Europe.
