Time difference between Istanbul and Athens
Athens is the same time as Istanbul
Istanbul, Türkiye is UTC+3 · Athens, Greece is UTC+2 — on standard time
The gap is not the same all year
Every converter gives one number for this pair. That number is right for most of the year and wrong for part of it, because Istanbul does not change its clocks and Athens goes forward on the last Sunday in March and back on the last Sunday in October.
| Istanbul / Athens clocks | Difference | How long |
|---|---|---|
| standard / summer | 0 hours | about 30 weeks |
| standard / standard | 1 hour behind | about 22 weeks |
