So this is June and your post has reminded me our anniversary was last month... we forgot, married 18 year this year. I would rather he show me love and consideration year round and me to him than save it up for anniversaries and valentines. I would worry about people who get so upset about such things as well as to me it would mean things were not good generally and your are hoping they will somehow redeem themselves
I just KNEW there would be someone who would come along and spout this garbage. 
Why assume if people like to make a fuss of their anniversary (or like their DH to make a fuss) or that they like to be remembered on Valentines etc, that they (or their partner,) don't care or show love and kindness for the rest of the year? Where does this wanky myth come from?!
Is it people who have partners who can't be arsed (or maybe who can't be arsed themselves!) trying to make excuses or convince themselves of something?!
Coz guess what? It is possible to have celebrations for birthdays, Valentines, and your anniversary, and STILL be a couple deeply in love, who care for each other immensely, and show love all year round! It's not one or the other you know. Just coz a man makes a huge fuss on Valentines or your anniversary, that doesn't automatically mean he is a shit husband for the rest of the year FFS!
Is this just people who have partners who do fuck all trying to make themselves feel better, coz they're jealous of the couples around them having great fun celebrating their anniversaries and valentines and birthdays? Whilst they and their partners do nothing and don't even exchange cards?!
And I don't believe for a second that you both 'forget.' 
Puts me in mind of a spiteful woman I used to work with who blathered on about she doesn't need HER boyfriend to prove he loves her by showering her with gifts for Valentines day.
'Oh you're pissed off that you got fuck all off him then?' Another colleague spouted!
