Changes by location


As it has in previous years, Morocco is suspending its DST period for the observation of the Muslim month of Ramadan from 03:00 on Sunday, May 5, 2019, to 02:00 on Sunday, June 9, 2019, in the Gregorian calendar.

During this period, clocks are turned back to Standard Time to shorten the evenings, making it easier for Muslims to observe the Ramadan fast during daylight hours.

On May 5, clocks are turned back at 03:00 to 02:00 to end the DST observation.
On June 9, clocks are set ahead at 02:00 to 03:00 to resume the DST observation.
