March 6th
March 6 is a "perfect sum" day because if we write today's date in the form 03/06/09, the sum of the month and day equals the year (3 + 6 = 9). Including today, how many "perfect sum" days are there in the 21st century?
Answer:
I do believe the answer is 365. No matter what day you choose, the sum of the month plus the day is less than 100. Naturally, February 29 does not get included, because 2 + 29 = 31, but 2031 is not a leap year.
