We all know about how the winter holidays always lead to a profound uptick in the number of packages your residents are receiving. But as ecommerce continues to rise exponentially, there are so many other times throughout the year when package delivery may surge at your properties. Check out our list of “Top 10 Hidden Holidays” you need to be prepared for:

1. Super Bowl Sunday. Once your team is out, you frantically buy gear for your de facto team of choice (let’s just say my son now owns a Falcons sweatshirt). Besides, how else are you going to get all football themes napkins, bowls, plates, etc. the Super Bowl Party?!

2. 100th Day of School. Yes, this is a thing and not something we made up. It’s mostly celebrated by younger students sometime in February, as schools have fun with the number 100. Many Pinterest-loving mothers are known to order craft items at this time, which can lead to a sneaky increase of packages in some circles.

3. Valentine’s Day. That oversized Vermont Teddy Bear isn’t going to drive itself to your significant other’s home. And neither is that sparkling necklace or whatever else you’ve ordered to make sure you’re not the goat on the international day of love.

4. Memorial Day. Everyone wants to get away for Memorial Day. But it’s even better to leave town with that new tent, new fishing supplies, new tarps and other camping accessories. Late May always leads to a package boom.

5. Independence Day. Yes, it’s illegal to ship fireworks by mail, so we’re not even going to go that route. But it’s also the heart of barbecue season and summer house parties, which leads to an uptick in online ordering of wide-ranging supplies.

6. Amazon Prime Day. The monster online retailer held its first holiday exclusively for its own “Prime” members in July 2015, predictably resulting in an online ordering frenzy. 2016’s Prime Day, which Amazon touted as “one-day-only global shopping event,” was even bigger. The retail giant has vowed to bring back Prime Day this year although an official date has not been announced. So what can we expect from this year’s Prime Day?! If it’s anything like last year when we saw more than a 30% increase in packages two days after Amazon Prime Day, it will be one of the biggest package delivery days EVER!

7. Back to School. Mid- to late-August means back-to-school time. This can create a sizable package rush, particularly for student housing communities. College students are continuing to seek alternative methods to purchase textbooks, such as sites like Chegg and eCampus, rather than buying them for full price on campus.

8. Labor Day. While Memorial Day unofficially signifies the beginning of summer, Labor Day serves as its end-of-summer counterpart. That means one last chance to escape the grind. It also means heavy discounts on outdoor merchandise as retailers look to make a push before camping season ends.

9. Pre-Halloween. While it’s a given that packages will arrive in droves during the Christmas season, this holiday can creep up on you. Some even call it a pseudo-holiday because no one ever gets the day off for Halloween, but expect a full package room as people continually opt to purchase their costumes online.

10. Home Events. As families convene, host homes don’t want to disappoint. While orders of kitchen and culinary supplies increase, families also commonly spruce up their homes to make a favorable impression on their visitors.
