It's collective memory: any housemate can add a date, and the whole house benefits from the reminder.

Why houses use it

Recurring by nature

Dates come back every year without re-entering.

Whole-house memory

One person remembers to add it; everyone gets the reminder.

On the calendar

Important dates appear in the shared calendar with everything else.
