Ever looked at a calendar in mid-January and felt that sudden, sharp spike of "Oh, I'm behind"? It happens. You’re staring down the barrel of a Q2 project, a major product launch, or maybe just the start of summer vacation, and you need to know exactly how much time is left. Not just days. Real, productive, sitting-at-the-desk hours. Calculating how many business days until May 22 is one of those tasks that sounds easy until you remember that Monday holidays exist and your brain forgets how many days are in April.
It’s about 90 days. Roughly. But "roughly" doesn't help when you're managing a supply chain or a construction permit.

Since today is January 13, 2026, we’ve got some ground to cover. We are looking at exactly 92 business days remaining until we hit May 22. This assumes a standard Monday-through-Friday work week and accounts for the major federal holidays recognized in the United States. If you’re in a different country, like the UK or Australia, your "May Day" or "Early Bank Holiday" is going to shift these numbers slightly.
The Breakdown: Why the Math Matters
Time is weird. We think in weeks, but we work in days. Between now and May 22, you’ve got about 18 weeks. That sounds like forever. It’s not. When you strip away the weekends—those 36 days where (hopefully) you aren't checking Slack—the window shrinks fast.
Let's look at the monthly chunks. January is already halfway gone. You have 13 business days left this month. February gives you a clean 19 days, assuming you take Presidents' Day off. March is a powerhouse with 22 business days because there are no federal holidays to slow you down. April adds another 22. Then you’ve got 15 days in May leading up to the 22nd.
Total: 91 or 92 days.
Why the discrepancy? It depends on if you count "today" as a work day or if the clock starts tomorrow. Most project managers at firms like Deloitte or McKinsey use "Day 0" logic. If you start the clock tomorrow, you’re at 91. If you’re grinding right now, it’s 92.
Federal Holidays and the "Hidden" Lost Days
In the US, the big one between now and May is Monday, February 16—Presidents' Day. Most banks, government offices, and corporate headquarters will be dark. If you’re waiting on a wire transfer or a building inspector that week, you effectively lose a day of momentum.
But there’s a trap.
Experienced operations managers know about "efficiency bleed." It’s not just the holiday itself. It’s the Friday afternoon before and the Tuesday morning after. People check out. If you’re calculating how many business days until May 22 for a high-stakes deadline, you should probably subtract another 3 to 5 days for general "human friction."
The "May 22" Deadline Phenomenon
Why May 22? It’s usually the last Friday before Memorial Day weekend in the United States. In the business world, this is a massive "hard stop."
If your project isn't done by the 22nd, it likely won't get looked at until the following Tuesday or Wednesday. Investors head to the Hamptons. Managers go off-grid. The 22nd represents the final gate of the spring season. If you miss it, you’re officially pushed into the "summer slump," where decision-makers are notoriously harder to pin down.
I’ve seen dozens of tech startups try to push a code release on May 23. It’s a nightmare. Nobody is there to fix the bugs.
Planning for the "April Lull"
April is often seen as a "full" work month because it lacks holidays. But according to data from workplace productivity apps like Asana and RescueTime, April often sees a dip in output. Why? Spring break. Even if you don't have kids, half your team probably does.
When you calculate how many business days until May 22, you have to look at the quality of those days.
- January 13 – Jan 31: High energy, "New Year" momentum. (13 days)
- February: Short, choppy, often interrupted by flu season or bad weather. (19 days)
- March: The "Slog." No holidays. High burnout risk. (22 days)
- April: The "Distraction Zone." Spring breaks and tax season. (22 days)
- May 1 – May 22: The "Sprint." Everyone realizes the deadline is here. (15 days)
Using the "Rule of 70" for Productivity
A common mistake in project management is assuming 100% capacity for every business day. It’s a lie. Realistically, most teams operate at about 70% capacity over a long period.

If we have 92 business days, your "effective" work days are actually closer to 64.
That realization usually changes the tone of the meeting. Suddenly, that May 22 launch feels a lot closer, doesn't it? If you’re a freelancer or a solo-entrepreneur, this is even more critical. You are the IT department, the marketing team, and the CEO. If you get a cold in March, you lose three business days. That’s nearly 5% of your total remaining time.
International Variations to Keep in Mind
If you are working with a global team, your "how many business days until May 22" calculation is going to be a mess.
In the UK, you have the Early May Bank Holiday (Monday, May 4, 2026). If your lead developer is in London and your project manager is in New York, that’s a day where communication dies.
In Japan, you have "Golden Week" at the end of April and beginning of May. This is a series of four national holidays. If you are sourcing components from Japanese suppliers, you basically lose an entire week of "business days" in that region. You can’t just count 92 days and call it a day. You have to map the geography of your workflow.
Strategic Steps to Hit the May 22 Target
Don't just count the days. Optimize them.
First, audit your calendar for "Blackout Zones." These are the weeks where key decision-makers are traveling. If your boss is at a conference in mid-April, you cannot count those as "decision business days."
Second, set a "Soft Deadline" for May 15. This gives you five business days of buffer. In my experience, something always goes wrong in the final week. A server crashes, a client changes their mind, or a key team member gets a better offer elsewhere. That final week should be for polishing, not for building.
Third, automate the mundane. If you're spending three of your remaining 92 business days doing manual data entry or scheduling, you're wasting roughly 3% of your remaining "life" on this project.
Moving Forward
Now that you know you have roughly 92 business days (depending on your specific local holidays and start time), the next move isn't to start a spreadsheet. It’s to prioritize.
Break your project into three "Sprints."
Sprint 1: Now until the end of February (The Foundation).
Sprint 2: All of March (The Heavy Lifting).
Sprint 3: April to May 15 (The Refinement).

Leave that final week of May 18-22 for "Emergency Only" tasks. If you do this, you won't be the person frantically emailing at 9:00 PM on May 21 while everyone else is packing for the long weekend.
Start by identifying your "Single Point of Failure." Who or what is the one thing that could stop this project on May 22? Reach out to that person or check that system today. January 13 is the perfect time to fix a problem that would otherwise blow up in April.
