"You will NOT use le when talking about weekdays in a specific context (on Monday):
Mercredi, tu iras à l'école.On Wednesday, you will go to school."
UNLESS "when giving a whole date (day/number/month/[year]), such as
Le mardi 5 mars, j'ai rencontré Lola.On Tuesday the 5th of March, I met Lola.
Par example on the test : Le mardi 6 janvier, j'étais malade.On Tuesday the 6th of January, I was sick.
HOWEVER< If the question was "On Tuesday I was sick" (without the whole date), it would be "Mardi, j'étais malade."
Is that correct?? Thanks
