WebbThis is Hipparchus's method as described by Ptolemy. However, Ptolemy used his own table of chords; I use the figures from Hipparchus's table as reconstructed by Toomer [103]. The basic data are that the interval from spring equinox to summer solstice is 94~ days and the interval from then to autumn equinox is 92~ days.
