Frequently asked questions
Why is India's timezone offset 30 minutes?
India Standard Time is UTC+5:30 — a half-hour offset chosen in 1906 to split the difference between two meridians. It is one of the few timezones with a 30-minute offset.
Does India have multiple timezones?
No. All of India uses a single timezone (IST, UTC+5:30) despite spanning roughly two geographic time zones. This simplifies nationwide scheduling.
What is the time difference between India and the US?
India is 10.5 hours ahead of US Eastern Time (EST) and 13.5 hours ahead of US Pacific Time (PST). The half-hour offset makes scheduling across these zones tricky.
