If 1st January, 2001 was a Monday, what was the day on 26th January, 2003?
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → Sunday
The weekday repeats every 7 days, so only the odd days, the days left over after whole weeks, move it forward. An ordinary year of 365 days is 52 weeks + 1 day, so the same date falls one weekday later in the next year.
2001 is not a leap year, 1 odd day: 1st January 2002 is Monday + 1 = Tuesday
2002 is not a leap year, 1 odd day: 1st January 2003 is Tuesday + 1 = Wednesday
26th January is 25 days after 1st January, and \(25=3\times7+4\), so 4 odd days
26th January 2003 is Wednesday + 4 = Sunday
