India Standard Time (IST) · UTC+5:30 · No Daylight Saving Time
India uses a single time zone for the entire country. Every city below shows identical IST time.
India uses a single national time zone: India Standard Time (IST), which is UTC+5:30. This makes IST one of only a handful of time zones worldwide with a 30-minute offset from UTC — most countries use whole-hour offsets.
India does not observe Daylight Saving Time. IST remains fixed at UTC+5:30 throughout the year. This means the time difference between India and DST-observing countries like the US, UK, and EU fluctuates by one hour between summer and winter — but India itself never changes its clocks.
Despite spanning over 29 degrees of longitude (roughly the same as the continental United States), India uses just one time zone for the entire country. This is a deliberate policy choice to maintain national unity — though it means sunrise and sunset times vary significantly across regions.
