Time Difference Calculator

Work out the exact difference between two dates and times, in days, hours, minutes and seconds — including when the gap crosses midnight.

Tokyo is +14h 0m ahead of New York right now.

New York: Wed 06:43 AM (UTC-05:00 · standard)

Tokyo: Wed 08:43 PM (UTC+09:00 · standard)

Yes — the difference changes during the year (from +13h 0m to +14h 0m) because at least one city observes DST.

How it works: both zones' offsets are read from Intl for right now, and again on the 15th of every month this year to see whether the gap ever changes. All offsets come from live timezone data.
