Calendars
Many ancient calendars are based on the cycles of the Sun or Moon. The Hellenic calendar incorporated these cycles. A lunisolar calendar based on both cycles is difficult. Some Greek astronomers worked out calendars based on the eclipse cycle.

Famous quotes containing the word calendars:
“Tomorrow in the offices the year on the stamps will be altered;
Tomorrow new diaries consulted, new calendars stand;
With such small adjustments life will again move forward
Implicating us all; and the voice of the living be heard:
“It is to us that you should turn your straying attention;
Us who need you, and are affected by your fortune;
Us you should love and to whom you should give your word.””
—Philip Larkin (1922–1986)
