What EET and IST Actually Are
EET — Eastern European Time
Athens, Helsinki, Bucharest, Kyiv, Cairo, Beirut. Standing at UTC+2:00 as written, and the region does change its clocks, so its live offset moves by an hour twice a year. The next change is on Sunday, October 25, 2026, to EET.
Eastern European Time is where the EU's synchronized clock changes meet countries that set their own dates, so the boundary between EET and its neighbors is less tidy than it looks.
IST — India Standard Time
Mumbai, Delhi, Bengaluru, Chennai, Kolkata, Hyderabad — and Colombo. Standing at UTC+5:30 as written, and the region does not change its clocks, so that offset holds all year. IST also stands for Irish Standard Time (UTC+1) and Israel Standard Time (UTC+2). This page covers the Indian one, which is by far the most searched.
India runs a single time zone across a country wide enough for two, which is why sunrise in the north-east can come nearly two hours before Mumbai's. Proposals for a second zone resurface regularly and have never been adopted.
What This Means in Practice
Expect times on the half hour
IST sits on a 30-minute offset rather than a whole hour, so a round number on one side is never a round number on the other. A 9:00 meeting becomes 30 minutes past the hour, which is exactly the detail calendar invitations get wrong when someone converts in their head.
This gap is not fixed
EET changes its clocks and IST does not, so the difference between them moves by an hour twice a year. A recurring meeting set now will drift for one side from Sunday, October 25, 2026 unless someone resets it.

Frequently Asked Questions
What is the time difference between EET and IST?
IST is 2 hours and 30 minutes ahead of EET. That is the live figure. Taken strictly as written, the gap between EET and IST is 3 hours and 30 minutes — the two differ because at least one of these regions is currently on daylight saving.
What is 9:00 AM EET in IST?
9:00 AM EET is 11:30 AM IST.
What are the best hours to schedule a call between EET and IST?
Between 9:00 AM and 3:00 PM EET, which is 11:30 AM to 5:30 PM IST. Both sides are inside normal business hours through that window.
Does the difference between EET and IST change during the year?
Yes. EET observes daylight saving and IST does not, so the gap shifts by an hour at least twice a year. The next clock change is on Sunday, October 25, 2026.
Does IST always mean India Standard Time?
IST also stands for Irish Standard Time (UTC+1) and Israel Standard Time (UTC+2). This page covers the Indian one, which is by far the most searched.
