'Calendrical' is almost identical to 'calendric,' also describing things related to calendars. Think of it as systems, calculations, or events pertaining to how we organize time. Calendrical calculations determine leap years and seasonal changes. It's subtly different from 'chronological,' which is about the order of events. 'Calendrical' emphasizes the structural and systematic aspects of calendars. The term indicates a deep involvement with the mechanics and usage of timekeeping systems.
