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
We are asked: Day of the week on 5 Nov 2021, given 5 Nov 2019 was Tuesday.
Step 1: Count the number of years
From 2019 → 2021 → 2 years
Step 2: Count the extra days
- 2020 is a leap year → 366 days → 52 weeks + 2 days
- 2021 is not a leap year → up to 5 Nov, the day shift is 1 day? Actually we only consider full years:
Better approach:
- From 5 Nov 2019 → 5 Nov 2020: 2020 is a leap year
- Number of days = 366 → 366 mod 7 = 2 extra days
- So 5 Nov 2020 = Tuesday + 2 days = Thursday
- From 5 Nov 2020 → 5 Nov 2021: 365 days → 1 extra day
- 5 Nov 2021 = Thursday + 1 day = Friday
