Abstract

The mean solar and lunar elements of all Chinese astronomical canons issued between 104 BC and AD 1644 are always obtained from fixed values of solar and lunar constants but the related calculations are not wholly identical in both cases because, on the one hand, Metonic canons also take avail of equivalences between given numbers of solar years and lunar months whereas, on the other hand, canons based on true elements only take the concerned mean values into account.
