Time and calendars
Find out about ancient ways of measuring time, and how calendars are constructed based on the cycles of the Sun and the Moon -and sometimes the stars.
- Ancient devices for measuring time: tally sticks, gnomon (part of a sundial that can be used alone without the actual "dial"), merkhet, water clocks.
- Definition of a month (particularly the first part of the article, until "Months in various calendars", you can then skip the rest if you wish).
