St. Patrick’s Day is a cultural and religious holiday observed every year on March 17th. Across the globe, people celebrate with parades, music, dancing, and, of course, by wearing green.
If you’re already looking forward to the next celebration, you might be asking yourself, “How many days until March 17th?” This article will show you how to calculate the number of days left until St. Patrick’s Day, including both the total number of days and the number of workdays remaining.
How long ’til March 17th?
The number of days between today and March 17th obviously depends on what day it is today. The calculations will change depending on when you’re doing the counting.
For example, if today is August 3, 2025, there are approximately 7 months and 14 days until March 17, 2026. That’s roughly 226 days between those two dates.
Here’s another way to look at it: 32 weeks and 2 days. Or 5,424 hours, give or take.
So, whether you’re counting down the days, weeks, or hours, you’ve got some time to plan your St. Patrick’s Day celebration!
How many work days are left until March 17th?
If you’re planning a project, knowing how many actual work days you have available is key.
It’s important to remember that the total number of days isn’t the same as the number of work days, because weekends don’t count!
So, how many work days are left? As of today, August 3, 2025, there are roughly 161 work days until March 17, 2026.
Keep in mind, though, that this number is an approximation. It doesn’t take into account holidays or personal time off.
To get a more accurate count, try using an online work day calculator. Many of these tools allow you to factor in holidays so you can see exactly how many days you have to work with.
You can also calculate work days using spreadsheet functions if you’re familiar with them. These functions also allow you to exclude holidays.
How to calculate the days until March 17th
There are a couple of ways to figure out how many days it is until St. Patrick’s Day. Here’s how:
Method One: Calculate the days manually
You can always grab a calendar and count the days one by one. If both dates fall within the same year, simply subtract the current date from March 17.
If the current date and March 17 fall across different years, you’ll need to first calculate how many days are left in the current year and then add that number to the number of days between January 1 of the following year and March 17.
Method Two: How to calculate the days using spreadsheet software (Google Sheets/Excel)
Spreadsheet software like Google Sheets and Microsoft Excel can do the math for you.
To calculate the days remaining from the current date, simply enter this formula into any cell: =DATE(2025, 3, 17) - TODAY() and press return. Be sure to change the year to the year you’re interested in!
If you’d rather calculate the days remaining from a different date, enter that date in cell A1 and use this formula in a different cell: =DATE(2025, 3, 17) - A1. The number of days between the date you entered and March 17 will automatically appear.
Putting It All Together
Whether you prefer to calculate the days until St. Patrick’s Day manually or using a spreadsheet formula, you now have several ways to figure out exactly how long you have to wait.
Use these techniques to plan your St. Paddy’s Day parties, budget for green outfits, or just get excited about the upcoming celebrations!
And don’t forget to factor in workdays, holidays, and travel time to make sure your plans go off without a hitch.
