What Does “Bimonthly” Mean? Definition and Examples

Does a bimonthly meeting on your work schedule occur twice a month or once every two months? Usually, we tell you it’s one or the other, but it could be either in this case. That’s right, bimonthly has two meanings, and there are times you’ll have to use context clues to determine which one is being referred to.

For example, a bimonthly publication with six issues per year refers to a periodical that publishes once every two months. A bimonthly pay schedule with 24 total paychecks per year means employees are paid once every other week; confusingly, this is also known as a biweekly pay schedule as well.

We’ll dive deeper into the meaning of bimonthly, provide synonyms, and discuss other words about time that use the bi- prefix.

What does bimonthly mean?

Bimonthly refers to events that occur twice per month or once every two months, depending on the context. If you say a bimonthly book club will meet six times per year, the word bimonthly means once every two months.

Bimonthly consists of the prefix bi- and the root word monthly. The confusion as to whether it means twice a month or once every two months comes down to the prefix. Bi- means “occurring every two” or “occurring twice.” In this case, monthly is an adjective that means “of or relating to a month.”

In other words, bimonthly has two definitions: twice a month or every two months. If you’re using this word to develop a meeting agenda, it’s important to be specific about which one you mean.

For example, if you say, “This bimonthly meeting will take place 24 times per year,” then people will know it takes place twice a month. Simply saying, “There is a bimonthly meeting on your calendar” leaves room for confusion.

The correct spelling is bimonthly and not bi-monthly. Hyphens are not used after the prefix bi- unless the root word starts with the letter I.

A bimonthly synonym is semimonthly, though that also doesn’t make the cadence clear without additional context. To avoid confusion, simply use phrases like “twice monthly,” “once every two weeks,” or “once every other month.”
