Okay. Heres some help:
For example, since July 31st was a Wednesday in 2019, we know it must be a Friday in 2020. (The Leap Day occurred in February 2020.)
From Edwin’s letter to Virginia, we can surmise the following three things:
This means if Edwin and Virginia’s wedding date was on a Saturday, eight years later should be a Tuesday, and if their wedding date was a Sunday, eight years later should be a Wednesday. But we know eight years after Edwin and Virginia’s wedding was a Monday. This can only occur if the eight-year period includes only one Leap Year. Hmm...what does that mean for the start date for our 8 years
- There are 365 days in each non-Leap Year.
- There are 366 days in each Leap Year.
- Leap Years occur every four years except in years that are divisible by 100, and except-except in years that are divisible by 400.
- Thus, 1900 is the only year in the 20th century that is divisible by 4, but not a leap year.

- The month in which they were married was January, June, or July.
- They were married on a weekend day.
- Eight years later, their anniversary was on a Monday.
