Times are converted through UTC using the offset each zone has on that date, so daylight saving is handled automatically. Some zones change their clocks on different dates each year.
Use this free time zone converter to convert a time from one city or zone to another. It’s daylight-saving aware, so meeting times across the world line up correctly.
What this time zone converter does
A time zone converter takes a date and time in one place and shows the matching local time somewhere else. It accounts for each zone’s UTC offset and daylight saving on that date.
How time zone conversion works
1. Convert the entered local time to UTC using the "from" zone's offset
2. Convert UTC to the "to" zone using its offset on that date
For example, 3:00 PM in New York on a June date is 8:00 PM in London and 4:00 AM the next day in Tokyo.

Why daylight saving matters
Many regions shift their clocks for part of the year, and they do it on different dates. That’s why the gap between two cities can change by an hour depending on the date — this converter uses the correct offset for the day you pick.

Time Zone FAQ
How do I convert between time zones?
Enter a date and time, choose the "from" and "to" zones, and the converter shows the matching local time — for example, 3 PM in New York is 8 PM in London.
Does it handle daylight saving time?
Yes. It uses each zone's correct offset for the date you choose, so summer and winter conversions are both accurate.
Why does the time difference change during the year?
Because regions start and end daylight saving on different dates, the gap between two cities can shift by an hour for part of the year.
What is UTC?
Coordinated Universal Time, the global reference. Every zone is expressed as an offset from UTC, like UTC−5 or UTC+9.
Can I convert a future meeting time?
Yes. Pick the future date and the converter applies the daylight-saving rules expected for that day.
Is the time zone converter free?
Yes, this time zone converter is completely free, needs no sign-up, and gives instant results in your browser.
