Etymology Origin:
The word "calendar" traces back to Latin calendarium, meaning "account book" (as debts were due on the calends, the first day of the Roman month). The calends derived from calare ("to call"), reflecting priests' role in proclaiming the new moon. Over time, it shifted from financial records to its modern timekeeping sense, retaining the core idea of "marking days."
