Also, the 'dating anniversary' thing has slightly confused me. When would I count mine...from the day we first hung out and realised we were interested? First one-on-one get together? When we acknowledged we were seeing each other? My boyfriend and I do have something we could point to as a first 'date', but lots of couples I know don't even have that--they more drifted together towards a relationship.
I've always thought of it as the day you decided to be exclusive, but not every couple has that conversation so exactly either. DH and I did but we never celebrated months or anything. It was Dec. 1 so it was easy to remember, though. Then we got married very close to that date (2.5 weeks before) so that not only took precedence as being more important, it also took away the dating
anniversary's even getting a nod. If we'd got married in June we'd probably spring for a nicer dinner in December as well, at least for the first few years.
My high school boyfriend and I celebrated months for the first year, but usually just with an acknowledgement, not with a big to-do (and I'd never expect my friends to remember)! We'd started dating
June 14, so the "big ones" were one month, six months, Valentine's, and 1 year.
