United States March deadlines

March 15 is the partnership and S-corp filing deadline (Form 1065 and 1120-S). Calendar-year C-corps with March-end quarters complete Q1 on March 31, kicking off earnings prep. Daylight saving begins on the second Sunday, which trips up after-hours trading desks running international books for the first overnight session.

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 23-day count in March 2005 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.

Frequently Asked Questions

How many business days are in March 2005 for United States?
March 2005 has 23 business days under the US federal holiday calendar. The month spans 31 calendar days, of which 8 fall on a weekend and 0 are US federal holidays that lands on a weekday. The remaining 23 weekdays are countable as business days for invoicing, deadline tracking, and contract math.
Which United States holidays affect March 2005?
March 2005 contains no US federal holidays that fall on a weekday. Banks, the central clearing system, and United States financial markets keep their normal schedule throughout the month under this calculator's national-only holiday set.
Why does this calendar differ from a state-specific calendar?
The 11 holidays this calculator uses come from 5 USC 6103, which governs federal employees and the Federal Reserve. State holidays such as Cesar Chavez Day in California, Patriots' Day in Massachusetts and Maine, or Confederate Memorial Day in some southern states are not in the federal set. State courts, the DMV, and state-chartered banks may close on additional days. For contracts that explicitly reference state-court business days, layer the additional state holidays into the calculator's Advanced options.
How do observed-day shifts work for US holidays?
When a fixed-date federal holiday falls on a Saturday, the federal observance shifts to the preceding Friday under 5 USC 6103(b). When it falls on a Sunday, it shifts to the following Monday. The bond market follows SIFMA's recommended schedule, which usually mirrors the federal observance. This calculator's holiday data lists the observed weekday rather than the literal calendar date, so a Saturday-falling Independence Day produces a Friday observed-day closure rather than the actual July 4 weekend day.
Why does the business-day count vary year to year?
Two things shift the monthly count for United States. First, the day of the week the first of the month lands on changes the count of each weekday. Second, US federal holidays anchored to a fixed date shift their weekday across years. Some years a fixed-date holiday lands on a weekend; some countries shift the observance to an adjacent weekday and some absorb it into the weekend. March 2004 also had 23 business days, so working capacity is unchanged year over year.
