As defined by OED, Anniversary is,

the date on which an event took place or an institution was founded in a previous year.

Is their any word in the same context which can be used for addressing the events after one month. For instance, I have to congratulate a friend on his marriage after one month.

P.S. I know that we can always keep it simple and convey the most, but I am just curious to know if there is any word equivalent to 'anniversary' but for the time period of one month.

    As it happens. the honeymoon derives from a custom of drinking mead (honey ale) for one month. But that's geeky and embarrassing. Sorry!

I have not found a word for this in the standard dictionaries. However, a common usage is--


MEN-SI-VER-SA-RY (mèn´se-vûr´se-rê) noun 1. The monthly recurring date of a past event, especially one of historical, national, or personal importance: a first date mensiversary; the mensiversary of the founding of Nerstone Pictures. 2. A celebration commemorating such a date. from Latin: mensis, month + versus, past participle of vertere, to turn.

If the word for the commemoration of a yearly event is anniversary, by analogy the logical word for the commemoration of a monthly event should be "mensiversary." "Anniversary" comes from the Latin "annum," meaning year. (The "versary" part comes from a Latin word referring to turning.) The Latin word for month is "mensis."

    That's the common usage? Funny how I've heard "monthly anniversary" umpteen million times, and this is the first I've seen of this Mensiversary word.

Especially when it comes to dating and relationships the term one month anniversary, two month anniversary is frequently used.


It's Ben's and my one month anniversary, so we're going out to a fancy restaurant for dinner.

  • Hmmm I'm not sure about the grammar of 'Ben and I's' anyone?

  • @JimMack Have edited it to 'Ben and my' and it still doesn't seem to make sense.

  • "Remember Ben? It's our anniversary..." (-: Actually, the "Ben's and my" you now have seems fine to me.

I always say lunaversary, which is etymologically just as justifiable, but doesn't have the same connotations to me (and other women) as mensiversary.

    add mooniversary. You just have to. Jun 27, 2015 at 4:11
  • I spell it luniversary. Jan 27 at 21:06

I did research and I found the word "mensiversary" and it refers to a celebration for every month. I'm positive it's what you're looking for as it's just like an "anniversary" but celebrated every month. also, I asked some people and found out some say "lunaversary" which is just like mensiversary. I did some research, and it's proved that this word is correct. therefore, you can also say "month anniversary" as it is thee most popular word for this term.

I'd like to suggest minaversary as an option. Derived from the Greek word for month - minas and -versary from anniversary. The connotation is twofold, it is monthly as well as minor, of lesser importance or lower in 'class' than anniversary.
