On the contribution of representatives of the muslim world to the development of chronological science (IX-XV centuries)

Since ancient times, the inhabitants of Central Asia have used a producing economy. In this way, they were helped by the skills gained by observing the movement ofcelestial bodies such as the Moon and the Sun. Our forefathers were able to accurately predict the timing of seed sowing, the irrigation season, and harvest time thanks to regular observation of their movement. These abilities developed over millennia and resulted in Chronology, the study of calculating time. The research of several Central Asian scientists who made a significant contribution to the development of chronology is the subject of this article.
