Fortnight

It's the same number of syllables, it means the same thing and uneducated people will (hopefully) understand you. I think it's better to say "two weeks" but I am from the U.S.A

This has actually blown my mind. I thought everyone used it. Huh.

We will be there in two weeks. We will be there in fortnight.

I am flabbergasted!

Is this for real? We use it in ordinary parlance!

America used to use it, just like they used to use "score" for 20 years. Then they realized there wasn't really any point to it. Why go 1 week, 1 fortnight, 3 weeks, 2 fortnights, etc. When you can just say 1 week, 2 week, 3 week, 4 week, etc. and no need to do any math to figure out what the person is talking about. Even if it is "easy math" that you just automatically do in your head, its unnecessary. Kind of similar to French numbers and how everybody thinks its complicated and weird, same for this.

I'm American, but I've read so many books by British people that I switch between terms, and even accents, but it doesn't surprise me when others don't know what a fortnight is, cuz the first time I said it, my friends looked at me like I was retarded

Wow it never occurred to me that they didn't say fortnight... We say it in Australia

The word is used now, just means something else
