Every hour in the UAE with the matching India time. Dubai office hours are in full color; +1 marks times after midnight in India.

A gap that never moves

The UAE keeps UTC+4 and India keeps UTC+5:30, and neither uses daylight saving, as the IANA time zone database shows for Asia/Dubai and Asia/Kolkata. That makes this one of the simplest pairs to convert: there are no switch dates to remember, and a meeting booked today will still be at the same time in six months.

The only thing to watch is the half hour. A 9:00 AM start in Dubai is 10:30 AM in India, not 10:00 or 11:00.

Calling home after work

Millions of Indians live and work in the UAE, and the evening call home is part of daily life. Finishing work at 6:00 PM in Dubai means it is 7:30 PM in Kerala or Mumbai, a good time to catch family before dinner. A late call at 10:00 PM in Dubai reaches India at 11:30 PM, which is late for most households.

The weekly rhythm also differs. Since 2022 the UAE government week runs Monday to Friday with a half day on Friday, close to India's working week, so weekend calls now line up on Saturday and Sunday for most people.

GST to IST questions

How far ahead of Dubai is India?

One hour and thirty minutes, on every date. Neither the UAE nor India uses daylight saving.

What is 7:00 PM in Dubai in India?

8:30 PM the same evening in India.

Which GST is this?

Gulf Standard Time, UTC+4, used in the UAE and Oman. The same letters are sometimes used for South Georgia Time (UTC−2), which has nothing to do with the Gulf.

Is Qatar or Saudi Arabia on Gulf Standard Time?

No. Qatar, Bahrain, Kuwait and Saudi Arabia use UTC+3, one hour behind Dubai and 2 h 30 min behind India.
