Time ZonesAbout this time zone
All of Sudan keeps one time. Computers and phones know it by the zone name Africa/Khartoum. Its time is UTC+2, which means it is 2 hours ahead of Coordinated Universal Time (UTC) all year round. The short name used for this time is CAT. Compared with India (IST), it is 3 hours 30 minutes behind India.
Clock changes in 2026 and 2027
Sudan does not change its clocks in 2026 or 2027. The time stays at UTC+2 all year, so there is no daylight saving time to remember.

Clock time and sun time in Sudan
A time zone is an agreement, and the sun does not follow it exactly. Khartoum, the largest city in this zone, lies at about 32.5° east. Each degree of longitude is worth four minutes, so by the sun alone its time would be about 2 hours 10 minutes ahead of UTC. The clock is set to UTC+2. The sun is therefore highest in the sky at about 11:50 am 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 Khartoum, 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
Khartoum is about 15.6° north of the equator. On the longest day of the year, around 21 June, the sun is up for about 13 hours 3 minutes. On the shortest, around 21 December, for about 11 hours 12 minutes. The difference between summer and winter is about 1 hour 51 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 Sudan.
