Questions people actually ask
- Are weekends and public holidays counted?
- Both are counted here. Every day is a day. 7 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), 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?
- Sat, October 3, 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.
