If 18th February 1997 fell on a Tuesday, then what was the day on 18th February 1999?
Answer & explanation
Correct answer: option 4
The correct answer is Option (4) → Thursday
The weekday moves forward by the odd days, the days left over after whole weeks. An ordinary year of 365 days is 52 weeks + 1 day, so the same date one year later falls one weekday later; it falls two weekdays later only if a 29th February lies in between.
18 Feb 1997 to 18 Feb 1998: no 29th February in between (1998 is not a leap year), 1 odd day: Tuesday + 1 = Wednesday
18 Feb 1998 to 18 Feb 1999: no 29th February in between (1999 is not a leap year), 1 odd day: Wednesday + 1 = Thursday
