This UTC to IST converter turns any time in Coordinated Universal Time (UTC) into India Standard Time (IST), using your device clock so daylight saving is applied automatically. IST is 5 hours 30 minutes ahead of UTC. UTC is UTC+0; IST is UTC+5:30.
UTC covers Reykjavik (same clock), servers and aviation; IST covers Mumbai, Delhi, Bengaluru. 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 UTC and IST?
IST is 5 hours 30 minutes ahead of UTC. That comes from the UTC offsets: UTC is UTC+0 and IST is UTC+5:30. For example, 9 am UTC = 2:30 pm IST.
Is IST ahead of or behind UTC?
IST is 5 hours 30 minutes ahead of UTC, so when it is noon in UTC it is 5:30 pm in IST. Ahead means the clock there already shows a later time; a call at 5 pm UTC lands at 10:30 pm IST.
Does UTC or IST observe daylight saving time in 2026?
No. Neither UTC nor IST changes its clocks, so the 5 hours 30 minutes difference holds every day of the year. That makes recurring meetings between Reykjavik (same clock) and Mumbai easy to keep at a fixed local time on both ends.
What is the best time for a meeting between UTC and IST?
Standard office hours (9 am to 5 pm) overlap from 9 am to 11.5 am UTC, which is 2.5 pm to 5 pm IST. 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 UTC and IST?
UTC (Coordinated Universal Time) is used in Reykjavik (same clock), servers and aviation. IST (India Standard Time) is used in Mumbai, Delhi, Bengaluru, Kolkata. Some cities inside a zone skip daylight saving, noted in parentheses, so their offset matches only part of the year.
