At the same time of His Holiness the 7th Karmapa Tchödrak Gyamtso (1454-1506), the famed Tsurphu scholar, Jamyang Tchenmo Döndrup Öser composed numerous deep instructions on the 3rd Karmapa's treatise and worked out the fundamental charts needed for the annual calendrical calculations. From then on the Tsur system spread far and wide.

The 1st Jamgön Kongtrul Yönten Gyamtso (1813-1899) completed the compilation of the unfinished manual Tsishung Legshey Kuntu and numerous scholars were thus able to employ this astrological system. During the time of His Holiness 15th Karmapa Kakyab Dorje (1871-1922) and of His Holiness the 16th Karmapa Rangjung Rigpe Dorje (1924-1981), the most learned court master of calculations Ketcho Öser Rabten initiated a new approach to the Tsur system and compiles the data necessary for the yearly astrological almanachs.
