What day is it?

Alice is walking throught the forest of forgetfulness.
She wants to know what day of the week it is.
She stops and asks a lion and a unicorn.
Now the lion lies all of the time on Monday Tuesday and Wednesday.
The unicorn always lies on Thursday Friday and Saturday.
Alice asks the lion what day it is,
he says “Well yesterday was one of my lying days.”
Alice can”t figure it out just from the lion”s answer, so she asks the unicorn
and the unicorn says “Yesterday was also one of my lying days.”
What day is it?”
