1,460 Year Cycle

1460 Year Cycle Since the traditional Egyptian calendar of 365 days fell about one-fourth of a day short of the natural year, the ancients assumed that the heliacal rising of Sirius would move through the Egyptian calendar in 365 x 4 = 1460 Julian years (that is, one Sothic peniod). http://www.kronos-press.com/sun-moon/
