A heatmap titled "Sunrise time in Morocco" shows the shift in sunrise times from 2007 to 2024 across each month (January to December). Colours range from light (earlier sunrise) to dark blue (later sunrise). Each row represents a different year, with daylight saving time and Ramadan periods marked. From 2008 onwards, daylight saving is observed in morocco, but it's start and end dates move to avoid Ramadan. In 2018, Morocco moves to permanent daylight saving, except during Ramadan.
