Odd day occurs when three consecutive odd numbers make up a date e.g. 09/11/13 (last o.d. in a
dd/mm/yy format).
1. How many times a century does it happen?
2. What is the longest period of time between 2 successive odd days?
(In reply to
No math on vacation by Steve Herman)
I count 33350 days:
From 9/11/1913 to 9/11/2005 is 92 years or 33603 days.
Subtract:
March 1 - April 1: 31
April 1 - May 1: 30
May 1 - June 1: 31
June 1 - July 1: 30
July 1 - Aug. 1: 31
Aug. 1 - Sept. 1: 31
Sept. 1 - Oct. 1: 30
Oct. 1 - Nov. 1: 31
Nov. 1 - Nov 9: 8
---
253
33603 - 253 = 33350
