We say every other day/week/month.

Is every other second/minute/hour or every other year/decade/century correct?

  • Sure. Why wouldn't they be?

  • Wow. I'm pleased to learn that they are used like this. Do they sound natural? Commented May 4, 2017 at 13:56
  • It depends on the context. I can't think of many things that are only done "every other decade," so I don't hear that very often. But in the right context, it would be fine. For example, "Paraguay holds a census every twenty years, during the year that ends with 5 of every other decade," or, "Make sure the patient gets her blood pressure checked at least once every other hour until she leaves the ICU."

"every other" can be used with mostly anything:

  • Every other day/week/month/year/decade/century/second/minute/hour
  • Every other trip/book/car/town/person/animal/ship/problem/planet/etc.

Merriam-Webster defines "every other" as:

  • all those that are different or separate from the person or thing that has already been mentioned
  • used to say that some repeated activity, event, etc., alternately happens and does not happen in consecutive named periods

TheFreeDictionary has more definitions:

  • person or thing every second or alternate person or thing
  • omitting the next but including the one after that, as a series or repetition of something
  • happening or existing regularly on every second one of the things you are counting
  • every second one in a series
  • each alternate
