Mast tracks current federal flag orders and known South Carolina local orders so residents, public buildings, schools, businesses, and local websites can quickly check whether flags should be at half-staff or full-staff today.
The South Carolina source in Mast is South Carolina Governor / governor.sc.gov, categorized as Official Governor Executive Orders And News Archive.
South Carolina does not publish a dedicated current-status page in the source registry, so Mast checks official notices and dated directives. Mast also uses the source to track historical South Carolina half-staff notices when dated orders are available.
South Carolina publishes signed flag-lowering executive orders, with accessible text alternatives, in the Governor's executive-order index. Mast uses that index as the primary order source and retains the Governor news archive as supporting coverage for announcements that may appear before a signed order. The importer parses one-day, same-day, sunrise-to-sunset, sunrise-to-noon, and open-ended interment patterns.
