A dance school opened on Wednesday, 24th January 2018. On which day of the week did it celebrate its fifth anniversary, on 24th January 2023?
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → Tuesday
The date moves forward by 1 odd day for each year of 365 days and 2 odd days for a year that contains a 29th February. Since 24th January comes before the 29th February, the leap day of a year falls in the step from that year to the next.
24 January 2018 to 24 January 2019: no 29th February, 1 odd day, total 1
2019 to 2020: 1, total 2
2020 to 2021: contains 29 February 2020, 2, total 4
2021 to 2022: 1, total 5
2022 to 2023: 1, total 6
6 odd days: Wednesday + 6 days = Tuesday
