Computed on a date when UTC is genuinely in force — using today would be wrong for half the year, because a standard-time abbreviation does not exist in summer.

Common questions

What is the difference between UTC and IST?
IST is 5 hours 30 minutes ahead of UTC. UTC means Coordinated Universal Time at UTC+0, and IST means India Standard Time at UTC+5:30.
Which time zone does this page use for UTC?
UTC. An abbreviation is not a time zone — it is a label a zone wears for part of the year — so every calculation here uses a named IANA zone and says which one. If you are writing code, use UTC rather than the string "UTC".
Does IST mean anything else?
Yes: Irish Standard Time at UTC+1, and Israel Standard Time at UTC+2. Ireland calls its summer time IST — four and a half hours behind India, and only in summer.
Is UTC a daylight saving abbreviation?
No. UTC is the standard-time abbreviation. When daylight saving is in force, the same zone uses a different one.
