Capital: Khartoum · Single time zone (CAT, UTC+2) · still one of Africa's largest countries even after South Sudan's 2011 independence.
METHOD: MUSLIM WORLD LEAGUE (MWL)Sudan sits roughly between 9°N and 22°N, a wide enough range that seasonal day-length does shift meaningfully across the country — though nowhere near as dramatically as at the high latitudes of a country like the UK. Khartoum, the capital, sits at the confluence of the Blue Nile and White Nile, a geographically significant meeting point that has anchored the city's importance for centuries. Sudan doesn't maintain its own dedicated calculation method, so the Muslim World League convention, widely used across the Arab world and West Africa, is applied here.
Sudan lost roughly a quarter of its former territory when South Sudan became independent in 2011, though it remains one of the larger countries in Africa, still spanning a wide range of latitude from the Egyptian border to South Sudan.
