Common Questions about Daylight Savings Time Changes in Iran

Frequently Asked Questions about DST in Iran
Does Iran observe Daylight Saving Time?
No, Iran does not observe Daylight Saving Time. Clocks stay on the same time year-round. Several countries near the equator and in low-latitude regions skip DST because daylight hours change little across seasons.
What time zone is Iran on after DST ends?
After DST ends, Iran returns to its standard time zone, Asia / Tehran (Asia/Tehran). Standard time is the country's year-round baseline; DST adds one hour to that during the warmer months.
Why doesn't Iran use Daylight Saving Time?
Countries near the equator gain almost no benefit from DST because day length barely changes across the year. Other countries have abandoned DST due to public opposition, energy studies showing little benefit, or to simplify scheduling. Iran falls into one of these categories.
