20 Business Days Ago
20 business days ago (October 14, 2026) is:
Tuesday, September 15, 2026
That is 29 calendar days, skipping 8 weekend days and 1 US federal holiday.
Based on US federal holidays. Use the calculator below to change country.
Step back 20 business days from today, skipping weekends and US federal holidays, and you get the date above. The useful version of this question is usually about the start of a period that has already run: when a notice arrived, when goods were delivered, whether an event still sat inside a window that has since closed. The result card adjusts to your local calendar once the page loads, and the calculator below lets you replace today with whatever fixed date you are working back from.
Twenty business days back is four full work weeks, and unlike most round numbers on this site it maps onto a real federal deadline counted in exactly these days. The usual reason to run it backward is to check whether an agency answered in time. Setting the deadline instead is 20 business days from today.
Checking a FOIA response after the fact
The Freedom of Information Act gives an agency "20 days (excepting Saturdays, Sundays, and legal public holidays)" to determine whether it will comply with a request, under 5 U.S.C. 552(a)(6)(A)(i). That is a business-day period in everything but name, and it is one of the few federal deadlines a member of the public can audit without any inside information: you know when you sent the request and you know when the determination arrived.
The audit is a backward count. Take the date of the agency's determination, count back twenty working days, and compare the result to the date the request was received. If the request predates it, the statutory period had already run. The complication to check before concluding anything is the extension in 552(a)(6)(B)(i), which allows a further ten working days in "unusual circumstances" if the agency gave written notice with the reasons and an estimated date. An extension used properly moves the whole analysis to thirty working days.

Four work weeks of reach
The calendar span below is the number to quote in a timeliness argument, because twenty working days is nearly a month of real time once weekends and any federal holiday are added back.
| What was counted | Figure |
|---|---|
| Total span in calendar days | 29 days |
| Working weeks behind us | 4 weeks |
| Elapsed weeks on the wall calendar | 4.1 weeks |
| Roughly how many months back | 1 month |
| Weekend days inside the lookback | 8 |
| Public holidays inside the lookback | 1 |
| Weekday of the earlier date | Tuesday |
Other backward twenty-day checks worth running the same way
The method transfers. Anywhere a commitment is expressed in working days, the same two dates and one backward count settle whether it was met.
- Service-level agreements that promise resolution in twenty working days, where the dispute is almost always about which holidays the vendor's calendar recognised.
- Public-records requests under state open-records laws, many of which copy the federal structure but not the federal holiday list.
- Procurement clarification windows, where a bidder needs to show a question was asked inside the period the solicitation set.
- Payment terms expressed in working days rather than calendar days. If yours is a plain Net term instead, the Net 30 calculator is the closer fit.
