Early civilizations tracked lunar cycles. A lunar month averages 29.5 days. Many calendars were lunar-based. Religious festivals still follow moon phases. The Moon guided agriculture and navigation. Human culture synced with it.
This matters because astronomy shaped society. Timekeeping evolved from observation. Science and culture intertwined.
It also shows lasting influence. Even modern calendars retain lunar roots. The Moon still marks time.
The word “month” comes directly from the Moon’s cycle.
