Convert IST to GST

India Standard Time (IST) to Gulf Standard Time (GST)

The India-Gulf corridor is driven by the massive Indian diaspora in Dubai, Abu Dhabi, and the wider UAE. Business calls, family calls, and IT services between Mumbai/Bangalore and Dubai are constant. The small 1.5-hour gap makes scheduling easy, but the 30-minute offset still trips people up.

Scheduling Tips

With only a 1.5-hour gap, standard business hours (9 AM-6 PM) overlap almost entirely. Schedule freely.
Keep in mind the UAE public sector moved to a Monday-Friday work week in 2022, though some private-sector businesses still follow a Sunday-Thursday pattern. Confirm your counterpart's work week.
The 30-minute offset means meetings at the top of the hour in India land on the half-hour in Dubai. Use :30 start times in GST for cleaner scheduling.

What is the time difference between IST and GST?

IST (India Standard Time, UTC+5:30) is 1 hour and 30 minutes ahead of GST (Gulf Standard Time, UTC+4). When it is 3:00 PM in Mumbai, it is 1:30 PM in Dubai.

Does the IST to GST time difference ever change?

9:00 AM IST is 7:30 AM GST. Both cities share almost the same business hours, making real-time collaboration straightforward throughout the workday.
