This IST to UTC converter turns any time in India Standard Time (IST) into Coordinated Universal Time (UTC), using your device clock so daylight saving is applied automatically. UTC is 5 hours 30 minutes behind IST. IST is UTC+5:30; UTC is UTC+0.
IST covers Mumbai, Delhi, Bengaluru; UTC covers Reykjavik (same clock), servers and aviation. Neither zone observes daylight saving time, so the difference is the same every day of the year.

Frequently asked questions
What is the time difference between IST and UTC?
UTC is 5 hours 30 minutes behind IST. That comes from the UTC offsets: IST is UTC+5:30 and UTC is UTC+0. For example, 9 am IST = 3:30 am UTC.
Is UTC ahead of or behind IST?
UTC is 5 hours 30 minutes behind IST, so when it is noon in IST it is 6:30 am in UTC. Ahead means the clock there already shows a later time; a call at 5 pm IST lands at 11:30 am UTC.
Does IST or UTC observe daylight saving time in 2026?
No. Neither IST nor UTC changes its clocks, so the 5 hours 30 minutes difference holds every day of the year. That makes recurring meetings between Mumbai and Reykjavik (same clock) easy to keep at a fixed local time on both ends.
What is the best time for a meeting between IST and UTC?
Standard office hours (9 am to 5 pm) overlap from 2.5 pm to 5 pm IST, which is 9 am to 11.5 am UTC. Pick a slot inside that window and both sides stay within a normal working day. Check the daylight saving dates above, because the window moves by an hour when only one side has changed clocks.
Which cities use IST and UTC?
IST (India Standard Time) is used in Mumbai, Delhi, Bengaluru, Kolkata. UTC (Coordinated Universal Time) is used in Reykjavik (same clock), servers and aviation. Some cities inside a zone skip daylight saving, noted in parentheses, so their offset matches only part of the year.
