What this tool does
Check today’s official holiday or operating status for common public services and markets.
Method
The engine combines official holiday calendars and published operating calendars. Business-specific hours require an official location record and are never inferred from a generic holiday alone.
Example
Check whether U.S. banks and USPS are generally open today and see the next relevant federal holiday.

Common questions
Is it free?
Yes. The core tool and its standard result or export are free to use.
Do I need an account?
No for the core utility. An account or private management token is requested only for capabilities that must persist, such as editable dynamic QR links.
Can I trust the result?
The method and assumptions are visible above. Time-sensitive tools name their sources and freshness; important financial, safety, legal, or operational decisions should be verified with the primary authority.
