What you call your wedding anniversary after you are divorced or separated.

Tomorrow I will be celebrating my 2nd nonniversary.

nonniversary

The day that would have been the anniversary of a relationship that failed.

Michelle: I would have been married to Oscar 12 years today... if he hadn't been a total cheating, lying douchebag that I divorced.
Amber: Happy nonniversary.
