The Huihui Lifa (Traditional Chinese: 回回歷法; Simplified Chinese: 回回历法; pinyin: Huíhuí Lìfǎ) was a set of astronomical tables published throughout China from the time of the Ming Dynasty in the late 14th century through the early 18th century. The tables were based on a translation into Chinese of the Zij (Islamic astronomical tables), the title Huihui Lifa literally meaning "Muslim System of Calendar Astronomy".
