"Ges i bythefnos o wyliau yn Sbaen."

Translation: I had a fortnight's holiday in Spain.

'Two week holiday' got rejected. Americans don't say 'fortnight'!

OK, that's a very good point, something we weren't aware of. I'll add it now.

Interesting point about language, in English 'fortnight' is a contraction of 'fourteen nights', which makes sense.

While in Welsh 'Pythefnos' is a contraction of 'Pymtheg noson' , which strangely means 'Fifteen nights'

[Estel785882]

That seems to be the same logic as "wythnos", a sort of inclusive counting that counts the beginning and end.
