The term "Veterans Day" is spelled without an apostrophe to indicate that the day is a day for honoring all veterans, not just one specific veteran or a possession or attribute belonging to veterans. The absence of the apostrophe sets it apart from possessive forms like "Veteran's Day" or "Veterans' Day."
