Yep. Good job.
If Ford lives past Veteran's Day, he will become the ex-President with the longest lifespan.
If the Post Office is closed on Friday, it's the day after T-Day. Whichever Pres was born the last week in November.
Post office isn't closed on the day after Thanksgiving. Veteran's day (Nov 11) is observed on the actual day rather than Monday, so November 11 is the day you're looking for.
