National Trivia Day: Thursday, January 4, 2024

Clean Off Your Desk Day: Monday, January 8, 2024

After the excitement of the winter holidays, it can be a struggle to get back into a productive mindset. Help employees out by scheduling an afternoon for desk cleaning—you can make it extra fun by incorporating competitions and prizes for things like the “Most Improved” desk. 

Bagel Day: Monday, January 15, 2024 

January Mondays can be gloomy. Give your employees a winter break by bringing in a delicious bagel treat, or sending them by delivery to your remote and hybrid employees.

Valentine’s Day: Wednesday, February 14, 2024 

Spread the love to your staff members with some sweet treats or other gestures of appreciation so they know how much you love their commitment to their colleagues, their roles, and the company as a whole. 

Random Act of Kindness Day: Saturday, February 17, 2024

While scheduled federal holidays are great, there’s also something extra exciting about giving and receiving just because. You can encourage employees to do something small but meaningful for each other on this day, like leaving a kind note or email for a colleague. 


National Employee Appreciation Day: Friday, March 1, 2024

You appreciate how hard your employees work every day—but this is the day to really make that appreciation known. And with these employee spotlight ideas, you’ll have plenty of ways to show recognition and appreciation to your workers in ways they’ll love. Don’t forget about other gifts to show you care too, like a lovely catered lunch or company swag. 

International Women’s Day: Friday, March 8, 2024  

Highlight the achievements and contributions of the women in your workplace on this international holiday! Show them how much they mean by offering some special snacks, a lunch ‘n learn on a relevant topic, or a small gift.

St. Patrick’s Day: Sunday, March 17, 2024  

It’s always fun to celebrate this holiday, even though it falls on a Sunday this year. You can encourage employees to decorate with or wear green to the office on Monday, and offer an Irish-themed menu in the cafeteria or have a remote happy hour with Irish tea and Guinness. 


National Pet Day: Thursday, April 11, 2024 

Many of your employees may have beloved pets at home, and this is a day to celebrate those furry companions. If your office is pet-friendly, you might allow employees to bring in well-behaved ones, or simply send them home with some company swag for their pets!

Cinco de Mayo: Sunday, May 5, 2024

International Human Resources Day: Monday, May 20, 2024

National Book Lovers Day: Friday, August 9, 2024  

Books have a way of bringing people together. For a change from the usual happy hour or snack offering, encourage employees to bring in their favorite book or organize an ongoing book club for colleagues to bond over their love of reading.

Halloween isn’t just for kids—it can be a great opportunity for your employees to dress up, decorate, share candy, and generally embrace their inner child (in a professional way, of course). 


Thanksgiving: Thursday, November 28, 2024 

While the paid time off offered on this federal holiday is great, don’t miss out on the team-building opportunities as well. Hold a pre-holiday lunch with all the classic Thanksgiving fixings, or give team members the chance to head out early for a happy hour the day before the holiday to bond.
