If it was a Wednesday on January 1, 2020, what was the day of the week on January 1, 2021?
Answer & explanation
Correct answer: option 4
The correct answer is Option (4) → Friday
The day of the week moves forward by the number of odd days (days left over after complete weeks) between the two dates.
2020 is a leap year (divisible by 4), so from 1 January 2020 to 1 January 2021 there are 366 days
\(366=52\times7+2\), so there are 2 odd days
Wednesday + 2 days = Friday
