Time Zone Converter

How to convert time between time zones

Select the city where the time is known in From, enter the date and time, then choose the destination in To. The result shows the converted local time, the date (which may be a day earlier or later) and the UTC offset that applies on that exact date. Use Swap to reverse the direction and Now to start from the current moment.

Why the date matters

A time difference is not always constant. If one place observes daylight saving time and the other does not, or if they switch on different dates, the gap changes. For example, the difference between New York and London is usually 5 hours, but for a few weeks in March and in late October/early November it is 4 hours because the United States and Europe change their clocks on different weekends. The converter applies the rules for the date you enter, so the result is correct even for future meetings.

Ambiguous and skipped times

On the night clocks spring forward, one hour does not exist locally; when they fall back, one hour happens twice. If you enter such a time, the converter uses the nearest valid interpretation. For critical schedules, avoid booking events between 01:00 and 03:00 on clock-change nights.
