If 5 November 2019 was Tuesday, then what was the day of the week on 5 November 2021?
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → Friday
The weekday repeats every 7 days, so only the odd days, the days left over after whole weeks, move it forward. An ordinary year of 365 days is 52 weeks + 1 day; a year that takes in a 29 February has 366 days, which is 52 weeks + 2 days.
5 November 2019 to 5 November 2020: the period takes in 29 February 2020, so it has 366 days, 2 odd days. 5 November 2020 is Tuesday + 2 = Thursday
5 November 2020 to 5 November 2021: no 29 February, so 365 days, 1 odd day. 5 November 2021 is Thursday + 1 = Friday
