Presidents' Day in the US is always on the third Monday in February.

Well, it depends. Some stores will lower some regular prices to entice customers to come to their store for the holiday shopping. They won't lower all the prices though, and often to get the best deals you have to be there early, since "supplies are limited." Some stores won't lower their prices for President's Day at all, both in the US which celebrates it, but also in other countries that don't.

The Uniform Monday Holiday Act made it so that most holidays are on Monday.

On president's day there is a big fun fair in Washington DC and you drink beer and eat corn dogs. Little kids go to the fun fair when the parents and adults go to a nearby pub. 5 and under go to day care. Hope this is helpful :)
