What is the time difference between Tokyo and New Delhi?

Tokyo (JST, UTC+9) is always 3 hours and 30 minutes ahead of New Delhi (IST, UTC+5:30). Neither city observes Daylight Saving Time, so this offset never changes throughout the year.

Does Tokyo observe Daylight Saving Time?

No. Japan abolished Daylight Saving Time in 1952 and has not used it since. Tokyo stays on JST (UTC+9) year-round.

Does New Delhi observe Daylight Saving Time?

No. India does not use Daylight Saving Time. New Delhi and all of India stay on IST (UTC+5:30) all year.

What are the best meeting times for Tokyo and New Delhi?

Tokyo business hours 09:00–18:00 JST correspond to 05:30–14:30 IST in New Delhi. The best overlap is 12:30–18:00 Tokyo (09:00–14:30 New Delhi), where both cities are within reasonable working hours.

Why is India's offset a half-hour? Is that unusual?

India uses UTC+5:30, a half-hour offset from UTC. This is deliberate — when India standardized time in 1906, it chose the meridian midway through the country. Several countries use half-hour or quarter-hour offsets, including Iran (UTC+3:30), Sri Lanka (UTC+5:30), and Nepal (UTC+5:45).

Is this tool accurate for scheduling?

Yes. It uses the IANA timezone database embedded in your browser — the same source used by operating systems and calendar apps worldwide. Accuracy depends on your device clock being synchronized via NTP, which most devices do automatically.

What does IST stand for?

IST stands for India Standard Time. It is UTC+5:30, used across the entire country of India year-round. There is no India Daylight Saving Time.
