IST vs EEST: what's the time gap?
EEST is 2 hours ahead of IST. In everyday terms, once you know the time on one side you just add 2 hours to get the other — so a call between Dublin and Athens is always 2 hours apart.
What's the current time in EEST?
Right now the time in Eastern European Summer Time (EEST) is Monday, June 29, 2026 · 8:53:59 PM. It ticks every second, so you’re always looking at the live EEST clock.
And what time is it in IST?
And in Irish Standard Time (IST), it’s currently Monday, June 29, 2026 · 6:53:59 PM. Compare the two and the 2 hours gap is easy to see.
What's the best time for a IST–EEST call?
For example, a 9:00 AM IST meeting takes place at 11:00 AM EEST. The trick is to aim for a slot that lands inside normal working hours on both sides. Once you’ve found a time, hit Share on the converter to copy a link with the time built in — easy to send to a colleague. Juggling three or more zones? The meeting planner highlights the hours that overlap for everyone.
Does daylight saving time change the IST–EEST difference?
The labels IST and EEST are fixed offsets, so the result on this page is always exact. Both regions move their clocks for daylight saving on roughly the same weekends, so the 2 hours gap usually holds steady right through the year.
How accurate is this IST to EEST conversion?
We don’t guess. IST and EEST times are worked out from the official IANA time zone database, the trusted standard that operating systems use worldwide. Because daylight-saving rules and regional offsets do change over time, we track those updates rather than relying on a fixed number — which is exactly where many converters slip up.

Frequently asked questions
How many hours ahead of IST is EEST?
EEST is 2 hours ahead of IST — a fixed 2 hours difference, since both are fixed-offset labels.
What time is it in EEST when it's 12:00 PM IST?
When it's 12:00 PM (noon) IST, it's 2:00 PM EEST.
Do IST or EEST use daylight saving time?
Irish Standard Time (IST) observes daylight saving, alternating with GMT; Eastern European Summer Time (EEST) observes daylight saving, alternating with EET.
Why might the real-world IST–EEST difference change during the year?
The labels IST and EEST are fixed offsets, so this converter is always exact. But Irish Standard Time's region switches between standard and summer time, so for part of the year you may actually want GMT to EEST. Always check which label a region is currently using before you schedule.
