It was the first holiday to celebrate the life of an individual American. The next would be Martin Luther King, Jr. Day, which was signed into law in 1983.
Today, Presidents Day is considered a day to celebrate all American presidents, past and present. Around the country, patriotic and historical groups hold events and celebrations and schools often teach students about the accomplishments of American presidents.
Last year, however, thousands of protesters across the country used their Monday off to protest President Donald Trump in "Not My Presidents Day" rallies.
"While we acknowledge that Donald Trump holds the current title, the policies he's trying to put in place are not the beliefs shared by the majority of the people," Nova Calise, one of the organizers of the New York event, told USA Today.
