How Mast works

Mast is an informational flag-status tool. It helps answer whether a U.S. flag should be flown at full-staff or half-staff, why the order is active, and where to verify the official source.

Checks public orders

Mast watches federal and state flag-status sources for half-staff orders, observances, and official notices.

Normalizes the details

Each detected order is organized by location, authority, start date, end date, and source so the current status is easier to read.

Shows the source

Mast is informational, so active orders include a source link when available and should be verified with the official notice when it matters.

Explains half-staff

Half-staff means lowering the flag below the top of the staff as a sign of mourning, remembrance, or honor for the period named in an official order.

Flag status reference

Mast answers a common question quickly: should a flag be at half-staff or full-staff today? The page shows the current status, the relevant authority, date range, and source when a known order is available.

The public API can also provide flag status data for websites, dashboards, signage, and small automations that need a simple JSON response.
