FishonaBike mused Yep, we definitely use "fortnight" here amongst the dark satanic mills. Never ever heard even a reference to se'ennight(s) though. Why not just say "week"?

I suppose you can have 5 or 6 day working weeks. Is that relevant?


You're assuming that the use of both fortnight and sennight were "designed". Like all such terms, my bet is that they just grew into usage. Fortnight just means "any fourteen-day period but let's not be either too exact about the number of days or assume that it begins on any particular day". Sennight was probably used in the same context. I assume its use died out when "week" - one syllable shorter - became more popular.
