You’re probably looking at a calendar and realizing that time moves way faster than it has any right to. If you are tracking a project, a fitness goal, or maybe a legal deadline, the math matters. 90 days from February 25 2025 lands you right on Monday, May 26, 2025.
That's Memorial Day in the United States.
It’s not just a random Monday. It’s a massive federal holiday. If you’re counting down these 90 days for business reasons—like a contract expiration or a notice period—you just hit a wall. Banks are closed. The post office isn't moving. Most corporate offices are empty. If your "90-day deadline" technically ends on that Monday, you effectively have to get everything done by Friday, May 23, 2025, or you’re already late.
People underestimate the "90-day" window. They think of it as three months. It isn't. Not exactly. February is the wrench in the gears because it’s short. In 2025, February has 28 days. Because of those missing two or three days compared to a standard month, your 90-day milestone arrives sooner than your brain expects it to.
The Math Behind 90 Days From February 25 2025
Let's break the count down. No fluff.
February has 28 days. If you start counting from the 25th, you only have 3 days left in February.
Then you add all 31 days of March.
Then you add all 30 days of April.
That brings you to 64 days.
To get to 90, you need 26 more days in May.
There it is. May 26, 2025.
Why does this specific count trip people up? It's the "Quarterly Trap." Many businesses operate on 90-day sprints. If you start a Q1-ending initiative on February 25, you aren't finishing in May—you’re finishing at the start of the summer season. In the productivity world, this is often called the "Spring Slide." You start with high energy in late February when the weather is starting to turn, but by the time day 90 hits, everyone is thinking about barbeques and three-day weekends.
The Memorial Day Conflict
Honestly, if you have a 90-day goal starting February 25, you need to account for the "Holiday Tax."

Since May 26 is Memorial Day, you lose a day of productivity. If you're a freelancer or a contractor waiting on a 90-day net payment, that money isn't hitting your bank account on Monday. The ACH transfers won't process. You're looking at Tuesday, May 27, at the earliest. It’s a small detail that causes huge headaches for cash flow.
Why 90 Days is the "Goldilocks" Zone for Change
Psychologists and habit experts, like those who reference the research of Dr. Maxwell Maltz or more modern studies from University College London, often talk about timelines. While the "21 days to form a habit" thing is mostly a myth—it actually takes closer to 66 days on average—the 90-day window is where the real physiological and neurological shifts happen.
If you start a health transformation on February 25, 2025, by May 26, you aren't just "trying" a new diet. You've actually replaced your old habits.
- Week 1-3: The Struggle. You're fighting muscle memory.
- Week 4-8: The Routine. It starts to feel normal.
- Week 9-12: The Identity. This is who you are now.
By the time you hit that 90-day mark on May 26, you've survived the weirdness of March weather and the rains of April. You’ve reached a point where your body has physically adapted to the stimulus you've been giving it.
Planning Your 90-Day Sprint (Feb 25 - May 26)
Most people fail because they treat 90 days like a marathon. It’s not. It’s a series of three 30-day blocks.
If you're looking at 90 days from February 25 2025, you should structure it like this:
The "March Madness" Phase (Days 1-34)
This takes you from February 25 through the end of March. This is your foundation. In the business world, this is often the most productive time of the year. People are back from winter breaks, and the Q3 slump hasn't hit yet. Use this time for the heavy lifting.

The April Calibration (Days 35-64)
April is notoriously tricky. You have tax season in the US, which sucks the life out of everyone’s focus. If your 90-day goal is financial, April is your hurdle. Don't plan big launches during the second week of April. People are distracted.
The May Sprint (Days 65-90)
This is the home stretch. From May 1 to May 26. This is where you polish. Since you know the finish line is a major holiday, you have to front-load your May work. If you haven't finished the bulk of your project by May 20, you’re going to be working through the weekend while everyone else is at the lake.
Don't do that to yourself.
The Seasonal Shift: From Late Winter to Early Summer
There is a psychological component to this specific timeframe. On February 25, much of the Northern Hemisphere is still dealing with the tail end of winter. It’s grey. It’s cold. You’re likely slightly Vitamin D deficient.
By May 26, 2025, everything has changed.
The environment you end in is completely different from the one you started in. This "seasonal bridge" is actually great for motivation. It’s much easier to finish a 90-day goal when the sun is staying out later. The increase in natural light helps with serotonin production, which can give you that final kick of energy to cross the finish line on Memorial Day.
Critical Deadlines to Remember
If you are a student, a project manager, or a legal professional, here are the specific dates you need to watch inside this 90-day window:

- March 10, 2025: Daylight Saving Time begins. You lose an hour. It sounds minor, but it messes with sleep cycles for about a week. Adjust your 90-day "energy budget" accordingly.
- April 15, 2025: Tax Day (US). Expect delays in communication from anyone in finance or administration.
- May 11, 2025: Mother's Day. If your goal involves personal time or travel, this is a "blackout" weekend.
- May 26, 2025: The 90-day mark. Memorial Day.
What If You Need "90 Business Days"?
This is a huge distinction. If your contract says "90 business days" starting February 25, 2025, you aren't ending in May. You’re looking at early July.
Standard 90-day counts include weekends. "Business days" exclude them plus holidays like Good Friday (April 18) and Memorial Day. Always, always clarify this in your contracts. If you assume calendar days and they mean business days, you're going to be waiting six extra weeks for that check.
Actionable Steps for Your 90-Day Window
You have the date. May 26, 2025. Now what do you do with it?
First, audit your calendar. Look at the last week of May right now. If you have a deadline on that Monday, move it to Friday, May 23. Do it now. You will thank yourself when you aren't trying to find a working printer on a holiday Monday.
Second, set a "Day 45" check-in. That lands on April 11, 2025. This is the midpoint. Most 90-day goals die between day 40 and day 50. If you can make it past April 11 with your momentum intact, you have an 80% higher chance of finishing strong by the May deadline.
Third, account for the February "Short Gap." Because February is 28 days, your first "month" of this 90-day period feels like it flies by. You’ll hit March 25 and feel like you’ve only been working for two weeks. You haven’t. You’ve been working for a full month. Don't let the short month trick you into thinking you have more time than you do.
Finally, plan your "Post-90" rest. Since the 90-day mark is Memorial Day, use that holiday as your reward. If you hit your goal, that Monday off becomes a celebration. If you don't, it becomes a day of catch-up. Use the fear of working on a holiday as fuel to get done early.
The count is simple, but the execution isn't. You have exactly 2,160 hours from the start of February 25 to the end of May 26. Use them.
