The U.S. Equities Market Holidays dataset provides authoritative reference information on trading calendar events that affect U.S. equities and equity options markets, including full market holidays and early market closes. The dataset delivers a historical record of market schedules from 1998 to the present, enabling accurate modeling of trading availability, session boundaries, and non-trading days. It is designed to support time-series analysis, back-testing, and operational systems that require precise awareness of market open, close, and holiday conditions. While U.S. market calendars are publicly available, this dataset consolidates and structures the information into a machine-readable, historical reference format, optimized for systematic ingestion and long-term analysis.
