Same moment around the world

Schedule meetings at the right time

Working out time differences when planning calls with clients abroad, international webinars or meetings with colleagues in other cities is confusing. The Time Zone Converter converts a date and time between two time zones accurately.

Features

  • Every region from the IANA time zone database built into your browser
  • Automatic detection of your local time zone
  • Daylight saving transitions applied correctly for the date you enter
  • A world overview showing the same moment in major cities

Offsets change during the year

Countries switch to daylight saving time on different dates, and some don't switch at all (Turkey uses UTC+3 all year), so the difference between two cities can change. The converter calculates it correctly for every date.

How to use Time Zone Converter

  1. Enter the source date and time.
  2. Choose the source and target time zones.
  3. Review the converted time and UTC offsets.
  4. Check other cities in the world overview.

Why use this tool?

Prevents missed meetings and planning mistakes caused by time differences.

FAQ

Does it account for daylight saving time?

Yes. Offsets are calculated for the date you enter, with summer and winter time applied correctly.

Why does the difference between two cities change?

Regions switch to daylight saving on different dates or not at all, so the offset varies through the year.

Are UTC and GMT the same?

In everyday use, yes; UTC is the scientific standard based on atomic clocks.
