State unemployment insurance returns close at month-end in most states.

United States reporting cycles and business-day rules
US business-day reporting cycles cluster on the 10th, 15th, and 25th of each month under IRS deposit schedules and SEC reporting rules. The Federal Reserve operates Fedwire on a 22-hour daily window with closure on all 11 federal holidays, so Saturday-falling holidays observed on Friday compress the prior week's settlement. ACH NACHA rules give a two-business-day standard for credit transfers and same-day options at three daily windows. Court filing deadlines under FRCP Rule 6 count business days for periods of 11 days or less and calendar days for longer windows.

Using this calculator in United States
A receivables analyst at a Long Beach freight forwarder uses the 19-day count in January 2027 to flag invoices whose Net 30 due dates land on Memorial Day or Independence Day, then reschedules ACH originations to clear before the holiday cutoff. A federal contracts officer uses the count to track FAR 32.905 prompt-payment windows across multi-task-order proposals. A Connecticut public-school district payroll lead uses the day-of-week distribution to schedule biweekly direct-deposit cutoffs on Wednesdays and avoid Federal Reserve closures.
