Video Summary

Mary calculates the sum of the digits of dates throughout the year. To find the largest sum, she considers both month and day digits. September yields the highest month sum with digits adding up to 9. For the days, the 29th offers the largest sum with its digits totaling 11. Combining the month and day sums on September 29th, 09/29, results in a total digit sum of 20 (9 from the month + 11 from the day). Thus, the largest sum Mary can calculate in a year is 20.
