The question that once made the contestant of Road to Olympia give up

The Road to Olympia contest in the third quarter of 2019, broadcast on June 9, posed seemingly easy but extremely difficult questions, leaving many contestants stumped.

In the final round, with the 80-point question package option, contestant To Duc Quang had to face the question: "Knowing that January 1, 2019 is Tuesday, what day is January 1, 2079?"

After almost 15 seconds, this candidate gave the answer “Tuesday”. However, this is not the correct answer. If you can figure out the answer to this question in a short time, you are definitely a smart person.
