Possible years for a given combination of the day of the week, month, and date

If you know the day of the week, month, and date, you can figure out the possible years. This works for the Gregorian calendar which repeats in a 400-year cycle. That means you can add or substract 400 from any of these years to find more years that have the combination of day, week, and date you put in.
