I have been a Kossack for 2 years now.
I missed my actual anniversary date because I was never very good at dates and things.
I blame my mother because she couldn't remember the date of my birth. She had a ball park date, so I know roughly when I was born, but not exactly. My siblings had the grace to be born in hospitals where other people noted the date and time of their births, so there was never any question about them.
They got birthday parties.
Because my mother gave birth to me unattended, she never remembered exactly when it happened. Therefore, when the month in which I was born (she knew that!) came around, she'd sometimes say something, but there was no party because she didn't know what day to have the party on.
With no personal birthiversary, I never got the whole indoctrination about the importance of dates to others. I am very, very bad about remembering significant dates for others. Birthdays, anniversaries, holidays...unless a Big Deal is made out of it and the only way to avoid knowing about it is to be a reclusive hermit, these days just roll right past me.
So, on January 1st, I mark a calendar with the important dates to my family and friends - and then I mark the date a week before those important dates so I can remember to buy gifts, cards, or plan something for them.
I should do that for my blogiversary...except it's really not that important. I just used this year's blogiversary to hopefully excuse me when I forget your significant dates.
Here, have a generic cake to celebrate all the special days I will inevitably forget (and try to ignore the flaw beside the yellow rosebud...I am not very good at cake decorating):
