Questions people actually ask

Are weekends and public holidays counted?
Both are counted here. Every day is a day. 10 marked days fall inside this span (Halloween, Thanksgiving, Black Friday, Christmas Day, New Year's Eve, New Year's Day, Martin Luther King Jr. Day, Valentine's Day, Presidents' Day, St Patrick's Day), and none of them changes the count. A public holiday is never deducted automatically, because which ones apply depends on where you are.
Which day does this count from?
Fri, October 2, 2026, in US Eastern time. The page is regenerated hourly, so around midnight it can be a few hours behind your own date if you are in another zone — the answer is stated rather than assumed, which is the point of printing the starting day at all.
