If 18th February 1997 fell on Tuesday then what was the day on 18th February 1999?
Answer & explanation
Correct answer: option 4
The correct answer is Option (4) → Thursday
From a date to the same date a year later the weekday moves on by 1 day for 365 days (52 weeks + 1 day), or by 2 days if a 29 February falls in between.
18 February 1997 to 18 February 1998: no 29 February in between (1997 and 1998 are not leap years), 1 odd day, so Tuesday + 1 = Wednesday
18 February 1998 to 18 February 1999: no 29 February in between, 1 odd day, so Wednesday + 1 = Thursday
Tip: What matters is whether a 29 February lies between the two dates, not only whether the year is a leap year. From 18 February 2000 to 18 February 2001 the weekday moves by 2, but from 18 March 2000 to 18 March 2001 only by 1.
