Do the paleo-Hebrew inscriptions of the Gezer calendar, dated around the 10th century BCE, suggest that at one time the ancient Israelites used a strictly lunar calendar?
The calendar is written crudely in paleo Hebrew on stone. The inscription goes something like:
"Two months of harvest Two months of planting Two months are late planting One month of hoeing One month of barley-harvest One month of harvest and festival Two months of grape harvesting One month of summer fruit"
The word "month" is translated to mean "moon", according to online sources. There's no indication of a possible 13th month; neither are any of the months named to give an indication as to when in calendar year did the harvest begin etc. This possibly suggests that the years were strictly lunar, with harvest time etc occurring in various months throughout a typical decade.
If it doesn't indicate a strictly lunar calendar, would it point to the notion that a typical year would've been pictured as 12 lunar months?
