Liu Xiaorong and the Qiandao calendar
The Qiandao calendar was made by Liu Xiaorong, promulgated in 1167 CE. He also made the Chunxi calendar — two from one hand.
Southern Song calendars changed often and rarely lasted more than a decade; calendrists were commonly impeached when eclipse predictions failed, and the calendar had then to be changed.
Eclipses and reform
A failed prediction of a solar eclipse was the usual trigger for reform. When the bureau’s prediction missed, its officers were impeached and the calendar had to be revised.
