Questions
Does India have daylight saving time?
No. India uses IST (UTC+5:30) all year. The gap to the UK, Europe, the US and Australia changes by an hour when those countries switch clocks.
When do the US and UK change their clocks?
The US moves clocks forward on the second Sunday of March and back on the first Sunday of November. The UK and EU change on the last Sundays of March and October. This tool uses your browser's built-in time zone database, so these rules are applied automatically.
What is the time difference between IST and US Eastern?
IST is 9 h 30 min ahead of New York during US daylight time (mid-March to early November) and 10 h 30 min ahead the rest of the year.
