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
