Why Choose Our IRST to AFT Converter
When someone in Iran suggests 9:00 AM IRST, that's 10:00 AM AFT. This converter shows the overlap so both sides agree on one slot — no back-and-forth.
Late-night IRST times can land on a different date in AFT because of the 1 hour offset. The converter labels "next day" or "previous day" next to the result so you never send a message a day early or miss a deadline.
Daylight Saving adjustments can widen or narrow the IRST–AFT gap by an hour. During transition weeks many people get it wrong. This converter pulls the current UTC offsets automatically, so the result is right even on the changeover day.
Product launches, sports matches, and webinars are often announced in IRST. Convert the event time to AFT so you know exactly when to tune in — with a 1 hour difference, a morning event in Iran falls during work hours in Afghanistan.
