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