I am working on a coding problem and I need to check whether a past date was a federal holiday. It is trivial and I have already pulled the historic planned holidays but there have been many federal holidays/non-working days that have been declared by Presidential Proclamation or Executive Order. These include the day before(or) after Christmas as was done last year, the day of mourning for Former President Ford and snow emergency days that affected federal operations in DC.
So the question is, does anyone know where there is a listing of these that can be counted upon to be reasonably comprehensive. Th4e only things I can find are lists of the statutory holidays.
Thanks
