February 21 USA Holiday?

What's open and closed on President's day, February 21 in the USA?
They're not saying anything about the holiday in the news.
Will people get a day off work on this holiday? Are the stock markets open on President's day?

I'm a little confused, can anyone please tell me what is open and closed on February 21?

Only people who work for the state or the federal government will have a day off from work.
All city, state and federal offices are closed. Banks are also closed.

Some schools also give the kids, faculty and staff the day off, too.
In the US, the stock market will remain closed but it is open elsewhere.
