Solution
- Let us assume the husband's birthday is on any day in March, say 1st of March.
- March 1st this year, falls on a Tuesday.
- We simply need to find another month where the 1st of that month also falls on a Tuesday.
- Going through a calendar for 2022, we have the following:
March 1st : Tuesday
April 1st : Friday
May 1st : Sunday
June 1st : Wednesday
July 1st : Friday
August 1st : Monday
September 1st : Thursday
October 1st :Saturday
November 1st : Tuesday
December 1st : Thursday
- The only other month that has Tuesday on the first of that month, is November.
- Also, if we decide to choose any other day in March, say, 9th, we see that 9th of November also falls on the same day of the week as 9th of March.
- Thus, we can conclude that the month of the Wife's birthday must be November.
(Note: This answer is predicated upon which year you begin counting. This answer uses 2022, but 2021 would have yielded a different answer)
Final Answer
The answer is NOVEMBER
