Time is weird. One minute you're scraping ice off your windshield, and the next, you're wondering how on earth it's almost April. If you're currently staring at your calendar and asking how many days until March 29th, you probably have a flight to catch, a wedding to attend, or maybe just a deep-seated need for spring to finally arrive.
Today is Thursday, January 15, 2026.
If we're doing the math right now, there are 73 days left. That includes today. If you don't count today and want to know how many full days are sitting between you and that morning coffee on the 29th, it’s 72.

Counting days isn't just about the number. It's about the "buffer." Knowing you have 73 days means you have about 10 weeks. Ten weeks is a lot of time to lose five pounds or finish a project, but it’s a terrifyingly short amount of time if you haven't booked your hotel for a spring break trip yet.
Breaking Down the March 29th Countdown
Let's look at the calendar logistics. We are currently in mid-January. You have the rest of January (16 days), all of February (28 days—2026 isn't a leap year, thank goodness for simple math), and then 29 days of March.

It sounds like a long time. It isn't.
January usually feels like it lasts for six months because of the gray skies and the post-holiday slump. February is the "fake" month that disappears in a blink because it's short. Then March hits. In the Northern Hemisphere, March is the ultimate teaser. It’s the month where you get one day of 65-degree sunshine followed by a week of freezing rain.
Why March 29th Matters in 2026
You aren't the only one looking at this date. In 2026, March 29th happens to be Palm Sunday. This kicks off Holy Week for millions of people worldwide. If you're planning travel to places like Seville, Spain, or Rome, this date is basically "peak season" ground zero.
Travel experts like Rick Steves often point out that Europe during Holy Week is a completely different animal. Prices for flights into major hubs often spike exactly around this 73-day mark. Why? Because the "early bird" window is closing. Most people book international travel 3 to 4 months out, but the procrastinators start panicking right around now.
The Psychology of the Countdown
Why do we obsess over how many days until March 29th or any other specific date? Psychologists call it "temporal landmarks."
Researchers like Katy Milkman at the University of Pennsylvania have studied how these specific dates act as "fresh starts." March 29th is deep enough into the year that your New Year’s resolutions have likely died a quiet death in a corner. Checking the countdown is often a way to reset. It’s a target.
Maybe you’re training for a half-marathon. 73 days is roughly 10 weeks. That is a classic training block length. If you haven't started your long runs yet, this is your wake-up call. Honestly, if you start today, you can still hit a decent time. If you wait until there are 40 days left? You’re going to hurt yourself.
Seasonal Affective Disorder and the March Light
There's a biological reason you're counting down to late March. By March 29th, the vernal equinox has already passed. We are gaining light.
In the Northern Hemisphere, the days are getting noticeably longer. For people struggling with Seasonal Affective Disorder (SAD), March 29th represents a turning point where the sun actually stays up past dinner time. It’s a light at the end of the winter tunnel.
- January 15th: Sunset is around 5:00 PM in many US cities.
- March 29th: Thanks to Daylight Saving Time (which starts March 8th in 2026), the sun won't set until nearly 7:30 PM.
That two-and-a-half-hour difference is a massive deal for your dopamine levels.
Historic Oddities and March 29th
History doesn't care about your countdown, but it’s interesting to see what has happened on this day while others were counting down to it.
Back in 1974, the Mariner 10 probe became the first spacecraft to fly by Mercury. It’s a reminder that while you're waiting for a date on a calendar, humans are out there doing wild stuff in the vacuum of space.
On a more terrestrial note, March 29th is often the peak of the Cherry Blossom festival in various parts of the world, though climate change has made this "peak" move around like a frantic squirrel. In 2026, experts are eyeing the last week of March for peak blooms in Washington D.C., and Kyoto. If you're counting down for photography reasons, those 73 days are your window to clean your lenses and prep your gear.
The Business of Late March
If you work in finance or retail, March 29th is the "clinch" date. It’s the end of Q1.
Most corporations run their first quarter from January 1st to March 31st. March 29th in 2026 is a Sunday. That means Friday, March 27th, is effectively the last real business day of the quarter.
- Sales teams are sweating their quotas.
- Logistics managers are trying to clear warehouses.
- Accountants are caffeinating for the madness of April.
If you’re wondering how many days until March 29th because of a work deadline, you actually have fewer days than you think. You have about 51 business days. That sounds much scarier than 73 total days, doesn't it?
Productivity Tips for the Next 73 Days
Don't just watch the clock.
If you have a goal for March 29th, break it down. 73 days is enough time to build a real habit. It takes, on average, 66 days for a new behavior to become automatic, according to a study by Phillippa Lally at University College London.
You literally have just enough time to start something today and have it be "second nature" by the time March 29th rolls around.

- The 10-Week Rule: Treat every 7 days as a "sprint." You have 10 sprints.
- The Buffer Zone: Aim to finish your goal by March 22nd. Give yourself a week of "grace" for when life inevitably gets messy.
- The Visualizer: Use a physical calendar. Crossing off a day with a red marker hits the brain differently than looking at a digital screen.
What to Do Right Now
Since we've established there are 73 days until March 29th, your immediate next steps depend on why you're asking.
If it's for travel: Check your passport expiration date today. Most countries require six months of validity beyond your travel date. If yours expires anytime in 2026, you are cutting it close. Renew it now.
If it's for a fitness goal: Don't wait for Monday. Monday is a trap. Start the "Day 1" of your 73-day countdown right now, even if it's just a 10-minute walk.
If it's for an event: Confirm your RSVPs. People are notoriously bad at checking their mail in January. A quick text to your guest list or your host can save a massive headache in March.
The time is going to pass anyway. You might as well be ready for it when the sun finally stays up late on that Sunday in March.
