Agreed.  For whatever reason, my assumption was that this was to be used in
an RPG CHAIN environment.

National holidays are specified by legislation.  I published a routine
(several years ago) called RTVHOLIDAY that calculates the date and day of
the week for every national holiday, from the years 1600-9999.  The
holidays included:

New Years Day
Martin Luther King Day
President's Day
Memorial Day
Flag Day
The Fourth of July
Labor Day
Columbus Day
Election Day
Thanksgiving Day
The Day After Thanksgiving
Christmas Eve
Christmas

This was all done by an RPG routine which was about 100 lines with
comments.  There was a trivial CL to up front it.

There is also a TAA TOOL called RTVHOLIDAY.  It uses a table, and goes from
1940 to 2039.  The holidays include:

Ash Wednesday
Martin Luther King Day
President's Day
Good Friday
Easter
Passover
Mothers Day
Memorial Day
Fathers Day
Labor Day
Columbus Day
Rosh Hashanah
Thanksgiving Day
Hanukkah

This is about 900 lines, and is all done in CL.
