Not quite an anniversary. The day you started dating, celebrated or recognized each month by each person in the couple, leading up to the anniversary.

Committing to an offical relationship by mutual choice, and celebrated on the first month after the date that you asked one another to be your partner.
Boy: Will you be my girl friend
Girl: Yes~


(one month later)


Girl: i got you something for our Montaversary.
Boy: Oh yeah. . . Thats so sweet. . . What is it?
Girl: Its a surprise
Boy: I got you something too~

(After exchanging gifts, on your Monthaversary, you are committed to one another.)

instead, of the traditional yearly anniversary, a monthaversary occurs once a month and it is usually celebrated by younger couples who are grateful their relationship has even survived a month
