〈（《玉海》：《調元曆》，蓋仿曹士蒍小曆之舊。 (Jade Sea: The Tiaoyuan Calendar largely followed the tradition of Cao Shuxun's small calendar.

唐建中時，曹士蒍始變古法，以顯慶五年為上元，雨水為歲首。 In Tang's Jianzhong era, Cao Shuxun first broke with ancient practice, taking Xianqing 5 as the superior origin and Rain Water as the year's beginning.
