French help‼️‼️‼️PLEASE THIS MAKES NO SENSE‼️‼️

Bonjour
I guess tou have to find out which day could be today, then it's easy to find yesterday, the day before yesterday, tomorrow and the day after tomorrrow..
so if -->
mercredi = aujourd'hui
mardi = hier
lundi = avant-hier
and then ...
jeudi = demain
vendredi = après-demain
it sounds ok to me ..............
so in English
if -->
Wednesday = today (aujourd'hui)
Tueday = yesterday (hier)
Monday = the day before yesterday (avant-hier)
and then ....
Thursday = tomorrow (demain)
Friday = après-demain (the day after tomorrow)
this makes sense to me ..... hope it does for U
HAPPY NEW YEAR !!
