Fasting hours for Muslims worldwide during Ramadan by selected locations in 2023
Ramadan
The Islamic calendar is based on the lunar year; therefore, it is ten days shorter than the Gregorian solar calendar. Thus, Ramadan will take place from the 23rd March to the 21th of April 2023. The fasting hours are calculated from dusk until dawn of each day for the whole of the month of Ramadan. Differing fasting times in different places result from the fact that the length of each day varies based on the latitude of each location and changes each day due to the Earth's orbit around the sun. However, there might be slight interpretational differences between different schools of thought and branches of Islam.
Muslim world
According to the latest estimations there are over 1.7 billion Muslims worldwide. It is estimated that that by 2026 the Muslim population will increase to over 2.98 billion narrowing the gap with Christianity, whose community is projected to grow to just over three billion by then. The majority of Muslims worldwide are located in Asia, though it is only a quarter of the continent’s population.
