Most of us need to refer to a calendar quite frequently to know what calendar date (day, month, year) corresponds to which day of the week
I do not do this frequently. It is maybe 2.5% of the reason I use a calendar. Am I an outlier?
My use cases of a calendar:
Daily: confirming activities for the day
~Bi-daily: setting an appointment with someone else.
Weekly: confirming activities for the week, and slotting in other activities.
Monthly: long range scheduling (includes the target use case, but needs other information to be worthwhile)
Annually: Transfer persistent events to following year calendar and archival. (Target use case, but only for events that are not linked to a specific date. Also requires additional information).
