Time Zone Converter

Convert a date and time from IST or any zone to cities worldwide, and find meeting hours that suit everyone.

About Time Zone Converter

This time zone converter changes a date and time from India Standard Time, or any other zone, into local times for cities around the world. It shows each city’s time and difference from the source, and daylight saving time is handled automatically, so IST to EST or IST to PST conversions stay correct all year.

A meeting planner highlights working hours in each city, making it easy to pick a call time for teams in India, the USA, the UK and elsewhere. Your city list is remembered in your browser. It is free, needs no sign-up and works on any device.

How to use Time Zone Converter

  1. Pick the date, time and source time zone (India Standard Time is the default).
  2. Add or remove cities in the list — your choice is remembered.
  3. Read each city’s local time and difference from the source.
  4. Use the meeting planner: green cells are working hours (9 am – 6 pm); tap a column to choose that hour.

Frequently asked questions

Does it handle daylight saving time?

Yes. Conversions use your browser’s built-in time zone database, so daylight saving changes in places like London, New York and Sydney are applied for the date you choose.
