7 Chord US Financial Markets Holidays and Early Closes

A reference calendar of U.S. fixed-income and money-market holidays and early closes, carrying FINRA and SIFMA designations for each date. The calendar supports determination of valid trading days, settlement dates, accrual periods, and business-day conventions — routine requirements for time-series standardization, backtesting, coupon and payment scheduling, and cross-dataset alignment in fixed-income research.
