biweekly

The word "biweekly" is a bit of a linguistic trickster because it can mean two different things! Most commonly, it describes something happening *every two weeks*. Think of it as "bi-" meaning "two" and "-weekly" referring to the seven-day cycle. This is the standard for many workplace paychecks, where employees are paid every other week.

However, "biweekly" can also mean *twice a week*, which is where the confusion starts. Because the word is inherently ambiguous, many people use "semi-weekly" when they mean twice a week to keep things clear. Whether you are scheduling a cleaning service or a team sync, the context—and often a quick follow-up question—is usually necessary to determine the exact frequency.

The word "biweekly" is notorious for causing confusion, and rightfully so! It belongs to a rare group of words that can serve as their own opposites in terms of frequency. It carries two distinct meanings: *once every two weeks (occurring 26 times a year) or twice a week* (occurring 104 times a year).

Historically, the most common usage—especially in North America—is "every two weeks." You will see this most often in professional settings: "The company issues paychecks on a biweekly basis," or "Our newsletter is published biweekly." However, the "twice a week" definition is equally legitimate in the dictionary, leading to frequent misunderstandings in scheduling. It is also often confused with "semi-monthly," which means twice a month (24 times a year), though they are not technically the same.

To avoid ambiguity, many speakers choose clearer alternatives. If you mean every two weeks, you might use the British term "fortnightly" or simply say "every other week." If you mean twice a week, "semi-weekly" or "twice weekly" are much safer bets. Next time you see "biweekly" on a contract or a calendar, it is always wise to pause and clarify: are we meeting twice this week, or are we waiting until the week after next?
