I have two best friends Hazard and Oscar. They are quite strange in making statements. One of them always lies on Mondays, Tuesdays, and Wednesdays and tells the truth on all other days of the week while the other lies on Thursdays, Fridays, and Saturdays and tells the truth on other days of the week.
Today at 5:30, they made following statements,
Hazard: I lie on Saturdays.
Oscar: I will lie tomorrow.
Hazard: I lie on Sundays.
Today is which day of the week?
