CST
Casablanca Summer Time
Casablanca Summer Time (CST) refers to Morocco’s daylight saving practice in the Casablanca zone, where clocks shift forward to UTC+01:00 during summer months—making evenings brighter and aligning working hours closer to European partners. While most of Morocco observes this seasonal shift, the country has at times adjusted or suspended DST for cultural or religious reasons, adding a unique rhythm to timekeeping here.
