Veterans Day - no apostrophe

Next month there are 2 American federal holidays - Veterans Day (always November 11th) and Thanksgiving (celebrated on the 4th Thursday of November - this year November 22nd).

Many libraries will be putting up signs - "Closed for Veterans Day." One of my pet peeves (gosh, there are so many) is misplaced apostrophes. And because of my family involvement, Veterans Day is important to me. So, please forgive me for this soapbox pitch . . . . "Veterans Day" has no apostrophe.

And good librarian that I am, here's my source from an FAQ on the website of the United States Department of Veterans Affairs:

Q. Which is the correct spelling of Veterans Day?
a. "Veterans Day"
b. "Veteran's Day"
c. "Veterans' Day"

A. Veterans Day (choice a, above).Veterans Day does not include an apostrophe but does include an "s" at the end of "veterans" because it is not a day that "belongs" to veterans, it is a day for honoring all veterans.
