About this pair
EET → IRST at a glance
Convert EET to IRST — Eastern European Time (Helsinki) is currently 1.5 hours behind Iran Standard Time (Tehran). A 9 AM EET deadline lands at approximately 10:30 AM IRST, and a 5 PM EET deadline at 6:30 PM IRST.
Because at least one of EET or IRST observes Daylight Saving Time, the offset gap shifts by an hour twice a year. The converter below uses the IANA timezone database to pick the correct offset for your selected deadline date.
