Neither India Standard Time nor Gulf Standard Time changes its clocks in the next 18 months.
India Standard Time is UTC+5:30 all year. The whole country keeps a single clock, and India has not observed daylight saving time since the 1940s, so IST never changes.
IST can also stand for Irish Standard Time or Israel Standard Time. On this site IST always means India Standard Time (Asia/Kolkata).
Gulf Standard Time is UTC+4 all year. The UAE and Oman do not observe daylight saving time.
GST can also mean South Georgia Time (UTC−2). Here GST means Gulf Standard Time (Asia/Dubai).
Gulf Standard Time is 1 hour 30 minutes behind India Standard Time all year.
Dubai uses Gulf Standard Time. Gulf Standard Time is 1 hour 30 minutes behind India Standard Time all year. Type any IST time into the IST to GST converter to see the Dubai time for any date.
9:00 AM IST is 7:30 AM GST.
12:00 PM IST is 10:30 AM GST.
10:00 AM IST is 8:30 AM GST.
5:00 PM IST is 3:30 PM GST.
No, GST is behind IST. Gulf Standard Time is 1 hour 30 minutes behind India Standard Time all year.
Working days of 9 AM to 5 PM overlap from 10:30 AM to 5:00 PM IST, which is 9:00 AM to 3:30 PM GST.
