Time in Chennai, India

Time zone: IST (UTC/GMT +05:30) — Asia/Kolkata

Chennai keeps IST (5 hours 30 minutes ahead of UTC, UTC+05:30). Its database zone is Asia/Kolkata — worth knowing if you are scheduling anything that has to survive a daylight saving change.

Clocks in Chennai stay put. With no summer-time switch, the UTC+05:30 offset is fixed and the differences shown below only shift when the other end changes.

Current gap between Chennai and cities people most often need to coordinate with. These figures already account for daylight saving where it applies.

Overlap of a normal working day, shown in Chennai time — outside these windows one side is off the clock.

No shared working window exists with New York, Los Angeles or Sao Paulo, so those calls have to sit outside somebody's normal hours.

Same zone, same time — each of these sits on Asia/Kolkata alongside Chennai, including through any clock change.
