Government holiday calendars for major desks. United States first; other English-speaking and high-traffic economies alongside. Sources cited on every page.
No — today is not a public holiday in United States
Each country desk lists public holidays from an official government source with a licence that allows republication. Year pages show every date, a month chart, and whether today is a holiday in that country.
Regional, provincial, or employer-specific holidays are not included unless they appear in the national reference list for that desk.
