Ghost Dates

Does anyone else collect ghost dates? I don’t mean literal potentially-romantic meetings with the corporeally dispossessed, or anything to do with ghosting (actually, I have a draft of a potential post on just this subject, perhaps I should polish and publish?). No, I mean birthdays, anniversaries, days that you used to need to remember. Only now, for a variety of reasons, you don’t. Sometimes I wonder how long it will take until there’s a full 365, with an added bonus of the 29th of February.
