About India Standard Time (IST)
India Standard Time (IST) is the time zone observed throughout India, with a time offset of UTC+5:30. The time zone is also used in Sri Lanka, where it is known as Sri Lanka Standard Time (SLST). The entire region uses this single time zone, and neither India nor Sri Lanka observes Daylight Saving Time, so the time remains consistent year-round.
