Pennsylvania has a statute designating holidays that specifically includes "the third Monday of February, known as Presidents' Day." 44 Pa. Stat. Ann. § 11. I find it interesting that Pennsylvania uses the possessive form, indicating that the day belongs to the presidents. By contrast, the federal holiday, Veterans Day, does not use an apostrophe indicating possession. The theory is that it is a day to celebrate all veterans (plural, not possessive). However, here too, Pennsylvania has designated it Veterans' (possessive) Day.
So, happy Presidents' Day Pennsylvania.
