UTC to IST Converter (Coordinated Universal Time to India Time)

IST is 5 hours 30 minutes ahead of UTC.

Coordinated Universal Time is the reference that most computer systems record. India Standard Time is UTC+05:30. Neither of them observes daylight saving time, so converting UTC to IST means adding 5 hours 30 minutes on every date of the year.

Developers, analysts and support engineers need this conversion whenever a log, database record or API response is stamped in UTC and the reader sits in India. Timestamps usually end in a Z or a +00:00 marker, which means the value is UTC.

How to use this tool

1. Pick a date and time in UTC. The date matters when daylight saving time is in force.
2. Read the matching time in IST, with both UTC offsets.
3. Use "Use current time" for now, or the tables below for a quick look.

Formula

IST time = UTC time − (UTC UTC offset) + (IST UTC offset)

The converter looks up both UTC offsets for the actual instant in the saved IANA time zone rules, so daylight saving changes are included automatically.

Example

Worked with the saved rules:

9:00 AM UTC on March 2, 2026 = 2:30 PM IST

6:30 PM UTC on August 3, 2026 = 12:00 AM IST (next day)

Time difference through the year

The difference depends on the date when either place moves its clocks. These are the offsets on two reference days, from the saved IANA rules:

Clock changes in 2026

Coordinated Universal Time and India Standard Time do not change clocks in this year, so the difference stays the same all year.

Hours that work in both places

Hours (on the January reference day) that fall between 8:00 AM and 8:00 PM in both UTC and IST:

Reading a UTC timestamp

A value such as 2026-03-10T03:45:00Z is 9:15 a.m. in India, the moment of the opening session on Indian stock exchanges. Adding 5 hours and 30 minutes can carry into the next date, so a UTC time after 6:30 p.m. falls on the following Indian day.

Unix timestamps count seconds since 00:00 UTC on 1 January 1970. They do not contain a zone, and the zone is only applied when the number is shown to a person. For India that step is adding 19,800 seconds.

Scheduling in UTC for Indian teams

Globally distributed teams often write meeting times in UTC so that nobody has to guess whose clock is meant. An Indian participant adds 5:30 to the invitation, and the figure never moves in spring or autumn.

Midnight UTC is 5:30 a.m. in India. Services whose daily quota resets at 00:00 UTC therefore refresh at 5:30 a.m. IST, and a release set for 12:00 UTC is 5:30 p.m. in India.
