Timezone Converter
TimeZoneSimple is a fast, free way to convert time between cities around the world. Whether you're scheduling an international meeting, planning a trip, or coordinating with friends, family, or colleagues overseas, this tool finds the correct local time instantly — across more than 100 cities, with daylight saving time handled automatically.
How to use the timezone converter
Select your starting city, or click "Use my timezone" to detect it automatically from your browser. Choose a date and time, then add one or more target cities to instantly see the corresponding local time in each. Results update automatically if you change the date, time, or city list, and refresh every minute so the "your time" row always reflects the current moment when you leave the date at today.
Each result shows the day of the week and the UTC offset for that city on the date you picked — useful because offsets change with daylight saving time, so the gap between two cities isn't always the same year-round.

About TimeZoneSimple
TimeZoneSimple was built to be a clean, distraction-free timezone conversion tool without unnecessary complexity. All conversions use the IANA timezone database (the same source used by browsers and operating systems) so daylight saving transitions are handled automatically and correctly for the date you pick — not just today's offset. No sign-ups, no downloads, no account required.
