Q. March 1, 2008 was Saturday. Which day was it on March 1, 2002? (UPSC Prelims 2008)
Answer: Friday
Notes: March 1, 2008 was Saturday. To find the day on March 1, 2002, we move backward year by year. Normally, the day shifts 1 day backward each year. However, if a leap day (Feb 29) occurs between the two dates, the shift becomes 2 days. Step-by-step: Total shift = 2 + 1 + 1 + 1 + 2 + 1 = 8 days back Since 7 days make a full week, 8 days back is the same as 1 day back. Saturday − 1 day = Friday Therefore, March 1, 2002 was Friday.
