Holidays in May 2024

Mon, May 27Memorial Day

The last Monday of May. Federal offices close along with the bond market and the NYSE. It marks the unofficial start of the US summer season, which has knock-on effects: warehouse and freight schedules shift earlier in the week, and finance teams often see a Friday-heavy invoice pre-funding pattern.

Using This Calculator

A receivables analyst running a Net 30 portfolio uses the 22-business-day count in May 2024 to project cash collections by Friday of each week and to flag invoices whose due dates land on the holidays listed above. A project manager scoping a sprint that starts on the first business day of May uses the calendar grid to slot stand-ups, design reviews, and customer demos onto live working days rather than weekends. A specialty contractor billing time and materials uses the day-of-week distribution to see how many Mondays and Fridays fall in May 2024, which matters for crews who set installation appointments at the start and end of each week and skip Tuesday-to-Thursday for travel-heavy jobs.

Frequently Asked Questions

How many business days are in May 2024?
May 2024 has 22 business days under the US federal holiday calendar. The month spans 31 calendar days, of which 8 fall on Saturday or Sunday and 1 is a federal holiday that lands on a weekday. The remaining 22 weekdays are countable as business days for invoicing, SLA windows, and contract math.
Are there any holidays in May 2024?
May 2024 contains one US federal holiday: Memorial Day on Monday, May 27. Federal offices, the Federal Reserve, and US capital markets close on each of these days. State holidays and bank-specific closures may add additional non-working days for narrower contract definitions.
How does May 2024 compare to May 2023?
May 2023 had 23 business days, so May 2024 has 1 fewer working day year over year. The shift is driven by where weekends and federal holidays fall on the calendar in each year, not by any change in the number of holidays themselves. May 2024 starts on a Wednesday and May 2023 started on a Monday, which determines how many of each weekday land in-month.
Why does the business-day count vary year to year?
Two things shift the monthly count. First, the day of the week the first of the month lands on changes the count of each weekday: a 31-day month starting on a Friday produces five Fridays, five Saturdays, and five Sundays, while one starting on a Monday produces five Mondays, five Tuesdays, and five Wednesdays. Second, federal holidays anchored to a fixed date (Independence Day, Veterans Day, Christmas Day) shift their weekday across years; some years the holiday lands on a weekend and the observance moves to the adjacent Friday or Monday, which keeps the business-day count steady but changes which weekday is excluded.
What if I need business days for a different country?
Use the country selector in the calculator above, or visit the dedicated country pages for the United Kingdom, Canada, Australia, India, the Philippines, France, Germany, Japan, Mexico, or Singapore. Each calculator excludes that country's national public holidays. The country comparison table further down this page shows the May 2024 business-day count under each of the eleven supported holiday calendars side by side.
