Location-aware status

Mast is an informational service for checking current U.S. flag status, understanding why flags are lowered, and finding the official notice behind an order. It also provides clearly separated context about federal holidays and national observances.
The service
Federal and state half-staff orders are published across government websites, press releases, proclamations, and status pages. Mast brings those notices together by location and date so the current answer is easier to understand without losing sight of the official source. Informational holidays and observances appear separately so calendar context is available without implying that every commemorative day is a half-staff order.

How it works
Mast checks known federal and state government sources for flag orders, notices, and status changes.
Dates, locations, authorities, and source details are normalized into a consistent record.
Applicable orders appear together in the status view, map, calendar, timeline, alerts, and API.
When AI assists with a summary or translation, Mast labels that content and keeps the original source available for verification.
Important context
Mast does not issue flag orders and is not a government agency. It is an independent reference that organizes public information. When the display of a flag carries legal, ceremonial, or operational importance, confirm the details with the linked official source.
