Morphology

perpetual + calendar

The noun phrase combines 'perpetual' (continuing indefinitely) with 'calendar' (a system or chart of dates) so its meaning — a calendar that works across many years without needing yearly replacement — is directly derivable from the parts. This compositional interpretation is straightforward and cross-linguistically common, so an average B1 learner who knows both words would be able to infer the MWE's basic function.

Etymology

Perpetual calendar gives a simple picture: a perpetual (never-ending) calendar that can tell the 'day of the week' for any date. Early versions were tables or wheels you set for months and 'leap years', so the name now means a calendar or watch feature that works correctly for many years.
