About Thoothukudi Time Zone

Thoothukudi does not observe daylight saving time, so its local clock does not change in March, October, or any other part of the year. This makes scheduling simpler than with countries such as the United States, United Kingdom, or Australia, where offsets shift seasonally; for example, the time gap between Thoothukudi and London is 5 hours 30 minutes during UK winter but 4 hours 30 minutes during British Summer Time.
Geographically, Thoothukudi is in the state of Tamil Nadu, near the Gulf of Mannar, and shares the same time zone as major Indian cities including Chennai, Mumbai, Delhi, Bengaluru, and Kolkata.
