The scientific study or calculation of the hours of the day, or the division and measurement of daylight and daily time periods.
From Greek 'hemera' (day) and 'logos' (word, study, discourse). The '-ology' suffix creates a field of study focused on the daily and hourly cycle.
Hemerology might sound obscure, but it was crucial to ancient and medieval life—before mechanical clocks, understanding the precise hours of daylight was essential for agriculture, prayer times, and navigation.
