The Bureau of Labor Statistics publishes the report, officially called the Employment Situation, usually on the first Friday of the month at 8:30 am New York time. The count comes from a survey of employers and leaves out farm workers, the self-employed and household staff. The unemployment rate comes from a separate survey of households.
A strong number is not always good news for markets. When the Federal Reserve is worried about inflation, a hot jobs market can mean higher rates for longer, so stocks and Bitcoin may fall on it. Earlier months are also revised, sometimes by a lot.
