Convert time from IRST to EDT. Enter any time to see the equivalent EDT time, compare current IRST and EDT times side by side, and find overlapping business hours for calls and meetings.
Use this IRST to EDT converter to compare Iran and US East Coast time, check the 7 hours and 30 minutes gap, and confirm the right slot for calls, handoffs, and deadlines. Good overlap starts around 5:00 PM IRST / 9:30 AM EDT.
Converting between Iran Standard Time and Eastern Daylight Time means accounting for a 7 hours and 30 minutes gap — here's how to do it in under 10 seconds with no sign-up.
Pick the date and time in Iran Standard Time (UTC +3:30) that you want to convert. Hit "Now" to load the current irst time instantly, or use "+1h" to step forward and compare.
The equivalent Eastern Daylight Time (UTC -4) time appears immediately. Since edt is 7 hours and 30 minutes behind of irst, most daytime conversions stay on the same calendar day.
Click "Copy Time" to grab the edt result for your calendar or message. Use "+1d" to check how the conversion shifts across dates — useful when Daylight Saving Time changes the gap.
When someone in Iran suggests 5:00 PM irst, that's 9:30 AM edt. 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 edt because of the 7 hours and 30 minutes 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.
The half-hour offset between irst (UTC +3:30) and edt (UTC -4) already makes mental math tricky — add Daylight Saving Time and the gap can shift further. This converter uses live UTC offsets, so you're always accurate.
Product launches, sports matches, and webinars are often announced in irst. Convert the event time to edt so you know exactly when to tune in — with a 7 hours and 30 minutes difference, a morning event in Iran hits the evening in United States.
