Tell Me Lies
Upon wandering through the forest, Alice came across a lion and a unicorn caught in a heated debate. They could not for the life of them figure out which day of the week it was, so they asked Alice to intervene and help.

There was a scroll in front of them that read: “The lion speaks the truth except on Mondays, Tuesdays and Wednesdays. The unicorn speaks the truth except on Thursdays, Fridays and Saturdays.” “I was lying yesterday”, said the lion, “Me too” replied the unicorn. Based upon the scroll information, on which day were they both lying? You don’t need a calendar so solve this one.
