the term "cake day" just makes me think of r*ddit. I've seen Lemon Day going around, but we probably want to avoid affiliation with lemon party.
not that we can tell anybody what to do anyway, and each instance could even have its own. anyway, it needs to be something that obviously means "anniversary" and doesn't require explanation otherwise it'll just be annoying
Well it doesn't help that they use the cake icon for it.
Not sure what else to propose calling it but anything else would be better.
On Hexbear I’ve only ever seen it called Molotov day
Mazel tov
a cake has been used to represent celebration of birthdays or anniversaries for longer than we've been calling them cake days
