Chennai does not change its clocks
A fixed offset, all year round
Chennai stays on India Standard Time at UTC+05:30 every day of the year. There is no spring-forward or fall-back here, which puts it with the majority: most of the world's time zones do not observe daylight saving.
That sounds like it makes scheduling simpler, and locally it does — but it introduces a different trap for anyone working with Chennai from a country that does change clocks. The offset between you and Chennai is not constant: it changes when your clocks move, even though nothing changed here. A recurring call that has run at the same local time for months will shift by an hour, from your side, without anyone editing the invite.
Chennai is not a whole number of hours from UTC
UTC+05:30 — 30 minutes off the nearest whole hour
Most time zones sit a whole number of hours from UTC. Chennai does not: it runs at UTC+05:30, offset by 30 minutes from the nearest whole hour. Only a handful of the world's zones do this.
It matters more than it sounds. Mental arithmetic that works everywhere else quietly fails here, and some scheduling tools round to the nearest hour — which puts a meeting in the wrong place by 30 minutes. If you are coordinating with Chennai, read the offset rather than estimating it.
When the gap to Chennai changes
Dates in the next year where the difference shifts, by counterpart city
