Time ZonesAbout this time zone
All of Oman keeps one time. Computers and phones know it by the zone name Asia/Muscat. Its time is UTC+4, which means it is 4 hours ahead of Coordinated Universal Time (UTC) all year round. Compared with India (IST), it is 1 hour 30 minutes behind India.
Clock changes in 2026 and 2027
Oman does not change its clocks in 2026 or 2027. The time stays at UTC+4 all year, so there is no daylight saving time to remember.

Clock time and sun time in Oman
A time zone is an agreement, and the sun does not follow it exactly. Muscat, the largest city in this zone, lies at about 58.4° east. Each degree of longitude is worth four minutes, so by the sun alone its time would be about 3 hours 54 minutes ahead of UTC. The clock is set to UTC+4. The sun is therefore highest in the sky at about 12:06 pm by the clock, not at 12:00. That is a close match: clock and sun agree to within a quarter of an hour. Other places in the zone, to the east or west of Muscat, see the sun peak a little earlier or later. Through the year the figure also drifts by up to a quarter of an hour either way.
How long the day is
Muscat is about 23.6° north of the equator. On the longest day of the year, around 21 June, the sun is up for about 13 hours 35 minutes. On the shortest, around 21 December, for about 10 hours 41 minutes. The difference between summer and winter is about 2 hours 55 minutes, and the clocks stay the same all year.
Office hours shared with other places
If both sides work from 9 am to 6 pm, these are the hours when a call falls inside the working day at both ends. Times are for Oman.
- With India, all year: 9:00 am to 4:30 pm here, which is 10:30 am to 6:00 pm in India (7 hours 30 minutes shared).
- With London, in January: 1:00 pm to 6:00 pm here, which is 9:00 am to 2:00 pm in London (5 hours shared). In July: 12:00 pm to 6:00 pm here, which is 9:00 am to 3:00 pm in London (6 hours shared).
- With New York, in January: no shared office hour: 9:00 am here is 12:00 am in New York, and 6:00 pm here is 9:00 am there, so one side has to start early or stay late. In July: 5:00 pm to 6:00 pm here, which is 9:00 am to 10:00 am in New York (1 hour shared).
