I don't understand how you can distinguish eg Friday from Fridays.

Question

I don't understand how you can distinguish eg 'Monday' from 'Mondays'. In the examples, there is a 'le' for both:
Le lundi est mon jour préféré - Monday is my favourite day
Je déteste le vendredi - i hate fridays

Bonjour Kez !
The issue in these two cases is whether "Monday/Fridays" are meant to refer to one single occurrence or in general.
When you say "Monday is my favourite day", you don't mean one specific Monday, but Mondays in general : in English, you could also say: "Mondays are my favourite".It's that encompassing meaning which justifies the use of "le".
I hope that's helpful!Bonne journée !
