## Method

Find the first date of Memorial Day on or after the start date, then count the days from the start date to it.

## Assumptions

- Memorial Day is the last Monday of May.
- Start dates from January 1, 1986 to December 31, 2400 work, because the US federal holiday rules used here start in 1986.
- The start date itself is not counted: from the day before, the count is 1; on the day itself, it is 0.
- Dates are calendar days with no time of day, so a time zone or a daylight-saving change never adds or loses a day.
