Razavi Khorasan, Iran

Current time in Razavi Khorasan, Iran

Local time throughout Razavi Khorasan is three hours and thirty minutes ahead of UTC. This national standard applies from Mashhad to the province’s western and eastern communities, so journeys within the region never require a watch adjustment.

The UTC offset remains unchanged during the year. International differences can still move because another country may use daylight saving time. A recurring Mashhad call that appears at one overseas hour in winter can consequently appear at another after the overseas clocks change.

The province is broad enough for many landscapes, but not broad enough to earn a second time zone.

Largest cities and regional clocks

Mashhad is the provincial capital and by far its largest city. Nishapur and Sabzevar are the next major urban centres, followed by cities including Torbat-e Heydarieh, Kashmar, Quchan, and Torbat-e Jam. All use Iran Standard Time.

Mashhad: the principal city and usual time reference. Nishapur: a major city west of Mashhad. Sabzevar: another large western urban centre. Torbat-e Heydarieh: an important city south of Mashhad. Kashmar, Quchan, and Torbat-e Jam: additional regional centres.

A single clock can represent the entire province, but one solar reading cannot. Razavi Khorasan extends far enough from east to west for location to matter when comparing sunrise or sunset. Select the actual city instead of assuming that Mashhad’s solar times apply everywhere.

Sunrise across a large province

Eastern places generally encounter sunrise earlier by civil time than western places on the same date. Latitude also affects seasonal day length, so the relationship is not based on longitude alone. Exact values require coordinates and a specific calendar day.

Terrain introduces a difference between calculated sunrise and first visible sunlight. A mountain or ridge may delay the moment when the solar disc can be seen from a valley. An astronomical service normally models the horizon in a standardized way and cannot describe every observer’s view.

For pre-dawn travel, distinguish astronomical sunrise from twilight. There may be natural light before sunrise, but its usefulness depends on cloud, street lighting, visibility, and the task being planned.

Scheduling in Mashhad and beyond

When arranging transport, accommodation, or calls, use the city’s local date along with the hour. This prevents ambiguity where a conversion crosses midnight. The Asia/Tehran identifier is preferable in calendar applications because it expresses the applicable regional rules.

Set the event in Iran time rather than using a nearby whole-hour zone. Confirm the date at both the origin and destination. Recheck recurring international meetings after foreign clock changes. Use city-level data for sunrise, sunset, dawn, and dusk.
