IST to Israel

About India Standard Time

India keeps one clock, UTC+5:30, across a country spanning about 29 degrees of longitude — the sun rises nearly two hours earlier in Arunachal Pradesh than in Gujarat on the same clock. The half-hour offset means most conversions from India land on the half hour rather than the hour. Sri Lanka keeps the same time.

Cities on this clock: Mumbai, Delhi, Bangalore, Hyderabad, Chennai, Kolkata, Pune, Ahmedabad.

Watch out: IST is also Israel Standard Time (UTC+2) and Irish Standard Time (UTC+1). This page is the Indian one.

About Israel Standard Time

Israel runs at UTC+2, moving to UTC+3 as IDT for roughly seven months. Its transition dates are set nationally and do not line up with the EU ones, so its gap to Central Europe is not fixed even though the two are usually one hour apart.

Cities on this clock: Tel Aviv, Jerusalem.

Watch out: IST means three different things: Israel Standard Time (UTC+2), India Standard Time (UTC+5:30) and Irish Standard Time (UTC+1). This page is the Israeli one.

How the difference is worked out

The gap between India Standard Time and Israel Standard Time is not one number. The two zones change their clocks on different dates, so for part of the year the difference is 2 hours 30 minutes and for the rest it is something else — the table above lists each stretch of 2026 with the date it starts and which country's clocks moved.

With both zones on their own standard time — daylight saving not in force anywhere — Israel Standard Time is 3 hours 30 minutes behind India Standard Time. That figure never changes; everything else on this page follows from it plus whichever clocks have moved.

Every figure here comes from the IANA time zone database via your browser's own Intl engine, using the zone ids Asia/Kolkata and Asia/Jerusalem. Nothing is looked up on a server and nothing about your visit is recorded.
