Timezone in Iran

Iran Standard Time (IRST)

The differences of the several time zones to each other are always specified in relation to the "Universal Time Coordinated" (UTC), the time on the prime meridian (zero longitude). The Iran Standard Time is consistent with UTC +3:30.

Countries with the Iran Standard Time, in which a switch to daylight saving time is common, turn the clock forward by 1 hour in summer. Like this they switch to Iran Daylight Time (IRDT) and reach UTC +4:30.

The Iran Standard Time applies only to Iran.
