Usage

What does bimonthly mean? Bimonthly is commonly used to mean one of two things: once every two months or twice per month.It can be used this way as an adjective, as in a bimonthly meeting, or an adverb, as in We plan to meet bimonthly. Yes, you can sometimes figure out what bimonthly means from the context of the sentence. But not always. The term bimonthly meeting might mean that it happens twice a month or every two months—both senses of the word are commonly used. Here’s the best (and maybe only) way to be perfectly clear: just say “twice a month” or “once every two months.”Bimonthly can also be used as a noun referring to a publication that’s published twice per month or once every two month (as opposed to a daily or weekly, for example).Examples:

  • New episodes of my bimonthly podcast come out on the first and 15th of every month. 
  • Let’s plan to meet bimonthly so we can fit in six meetings this year.
