India time to GMT

Subtract 5 hours 30 minutes from Indian Standard Time to find GMT. At 9 AM in India, it is 3:30 AM GMT. UTC is used as the zero-offset reference here and does not observe daylight saving time.

Find out what time it is in another city at any moment you choose. Compare up to eight destinations, see calendar-day changes and plan a time that works across borders. All calculations happen in your browser, with no account or external time service.

How to convert time zones

  1. Choose your starting city and enter its local date and time.
  2. Add the cities you want to compare. Each card shows the same moment in that location.
  3. Look for Yesterday or Tomorrow when the calendar date changes relative to your source.
  4. Copy a result, share the link, or open the meeting planner to compare working hours.

Understanding UTC and GMT

UTC is the international reference for civil time. GMT is a time zone with a zero-hour offset from UTC. For everyday scheduling, their displayed clock times agree. India uses UTC+5:30, which means its clocks are five hours and thirty minutes ahead of UTC.

Daylight saving time, without the guesswork

Some places move their clocks during the year. A city’s IANA time zone, such as America/New_York, includes those rules; a fixed offset does not. The converter uses your chosen date to find the right offset. When a clock change skips a local time or repeats it, the tool explains the issue and asks you to choose a valid occurrence. Keep your browser and operating system up to date for the latest time zone rules.

Frequently asked questions

What time zone is India in?

India uses Indian Standard Time (IST), UTC+5:30, throughout the year. Its IANA identifier is Asia/Kolkata. New Delhi, Mumbai and Bengaluru all use this time zone.

Does the converter handle daylight saving time?

Yes. It uses the time zone rules built into your browser for the date you select. If a local time occurs twice, choose the first or second occurrence. If it does not exist, choose another time.

What is UTC?

Coordinated Universal Time is the reference used to express time zone offsets. UTC itself does not change for daylight saving time.

Why does the time difference change during the year?

Different countries can change their clocks on different dates, or not change them at all. The difference between two cities can therefore vary even within the same month.

Can I compare multiple time zones?

Yes. Add up to eight destinations alongside your source city. Reorder, remove or change them, then share a link that preserves the selected cities, date, time and repeated-time choice.

How are overlapping working hours calculated?

The planner compares daily working hours over the selected source city’s calendar day, minute by minute. It supports overnight shifts and 23-hour or 25-hour days. Weekends and holidays are not excluded. Working-hour preferences are not included in shared links.
