Does JST or EET observe daylight saving time?+

Athens observes daylight saving time; Tokyo does not, so the gap changes when Athens springs forward or falls back. Times on this page always reflect the current local rules.

Standard 9–5 working hours in Tokyo and Athens overlap from 3 PM to 5 PM JST (9 AM–11 AM EET). Schedule calls inside this window to keep both sides in normal business hours.
