Current time in Kohgiluyeh and Boyer-Ahmad, Iran
The province follows the single national time used across Iran. Local time is three hours and thirty minutes ahead of UTC. There are no separate offsets for its counties, elevations, or urban areas. For a remote meeting, select an Iranian location in the calendar rather than a similarly named place elsewhere. The unusual half-hour offset makes informal mental conversion prone to error. Within the province, however, scheduling is straightforward because every community reads the same civil time.
Time system: Iran Standard Time Difference from UTC: three hours and thirty minutes ahead Local subzones: none Clock change during provincial travel: none Mountain roads may add time to the journey; they do not add time to the clock.
Main cities and regional centres
Yasuj is the provincial capital and the most useful general reference for time and local services. Other cities include Dogonbadan, Dehdasht, Likak, and Sisakht. All operate on the same official time as Yasuj and the rest of Iran.
The cities occupy contrasting landscapes. Yasuj and Sisakht are associated with mountainous surroundings, while Dogonbadan lies in a lower and warmer part of the province. Such differences shape climate and the view of the sky but never produce a legal time difference.
A provincial label is adequate for checking the current hour. For dawn, dusk, or weather, the city matters much more. A value calculated for Yasuj should not automatically be transferred to Dogonbadan or Dehdasht.
Sunrise in mountainous terrain
Astronomical sunrise is calculated from the Sun’s position relative to an ideal horizon. The actual first sight of sunlight can occur later when mountains or ridges stand to the east. Valleys may remain in shadow even though the published sunrise moment has passed.
The calculation also changes with the date and coordinates. Communities separated by longitude do not experience sunrise simultaneously, despite sharing a clock. For activities that depend on direct light, local observation and a terrain-aware forecast are more useful than a province-wide estimate.
Pick the nearest named city or exact coordinates. Check the requested date carefully. Confirm the result is expressed in UTC+3:30. Allow for eastern ridges and valley shadows.
Questions and answers
- Is Yasuj time the same as Tehran time?
- Yes. Both cities follow Iran Standard Time.
- Does elevation change official time?
- No. Elevation affects daylight and visibility, not the civil clock.
- Should I use Yasuj sunrise for Sisakht?
- Use Sisakht or local coordinates when accuracy matters because terrain and position differ.
