Employee engagement and recognition are year-round priorities for HR teams — but why not set aside a few extra special days to share your appreciation? 

Creating opportunities for shared celebration and appreciation is essential for building an engaged culture. Considering that a 2023 Gallup report found only 23% of employees are engaged, most workplaces could use a few more excuses to come together and celebrate.

If you’re looking for team building or event ideas, the below holidays may offer some inspiration. 

What is an employee engagement calendar?

An employee engagement calendar is your company's roadmap for making work more enjoyable. It can be a list of dates or even a detailed plan outlining activities and events scheduled throughout the year to boost happiness and loyalty.

In addition to lighthearted national holidays (e.g., “National Chocolate Chip Cookie Day”), HR teams might also want to include holiday parties and other annual company events.

Building an employee engagement calendar is one way companies can show that they want to develop a positive work environment. Simply, it's a tool that helps companies schedule fun and meaningful activities to keep employees engaged and happy at work.

National Employee Appreciation Day (Friday, March 1, 2024)

This year, “St. Paddy’s” falls on a Sunday. On the Friday before, decorate the office in green (or share festive Zoom backgrounds) and host a traditional Irish cooking class featuring staples like shepherd’s pie, corned beef and cabbage, and soda bread. 

Puppy Day (Saturday, March 24, 2024)
According to a 2021 study on dogs in the workplace, welcoming pets into the office may improve productivity. This year, Puppy Day falls on a Saturday.

Though this is technically puppy day, extend an invite to company kittens, parakeets, snakes, and other critters. 


Earth Day (Monday, April 22, 2024)
This international holiday celebrates environmental protection.

Started in 1949 by the Mental Health America (MHA) organization, Mental Health Awareness Month is widely observed around the world.

This holiday commemorates the Mexican Army's victory at the Battle of Puebla in 1862.

For a team so invested in everyone else's engagement, HR deserves its own holiday, too. International Human Resources Day offers a prime opportunity for a team lunch, field day, or other fun team-building activity. Make sure to include your remote colleagues, too.

Start of Summer (Thursday, June 20, 2024)

National 401(k) Day (Friday, September 6, 2024)
If your business offers retirement benefits or a matching program, make the effort to reiterate those offerings via a company-wide communication or by organizing office hours.

HR Appreciation Day (Thursday, September 26, 2024)
People teams endure a lot. You’re responsible for workplace culture, compliance, recruiting, benefits, reviews, and a long list of additional duties.

You can also appreciate other HR professionals in the Resources for Humans Slack group.


Mental Health Day (Thursday, October 10, 2024)

‍Halloween (Thursday, October 31, 2024)
Need new creative ways to celebrate Halloween at work? Besides the usual costumes, consider a pumpkin carving contest, horror film screening, or even a costume party for employees’ pets.

Thanksgiving (Thursday, November 28, 2024)
Ahead of the Thanksgiving holiday, show employees gratitude with a catered feast featuring all the fixings. While you might not be able to mail a plate to remote colleagues, a generous meal stipend could go a long way in showing your appreciation.


Giving Tuesday (Tuesday, December 3, 2024)
On the Tuesday after Thanksgiving, partner with a charity, community center, or school to give back to the less fortunate. Some ways to contribute include setting up a food or coat drive, donating gift cards to a shelter, or purchasing toys for a local children’s hospital. Make sure to publicize the event in advance of Thanksgiving, so employees can leverage Black Friday specials to give even more. 

Ugly Sweater Day (Friday, December 20, 2024)
What better way to ring in the holiday season than with an ugly sweater competition? In addition to organizing the usual contest between employees, you can also enroll in an ugly sweater 5K run for charity.

Winter Solstice (Thursday, December 21, 2024)
December is host to a slew of special holidays, so why not pick a day to acknowledge them all? The winter solstice marks the astronomical start of winter and the shortest day in the Northern Hemisphere. Celebrate your team with an office potluck or holiday party — or send them a surprise bundle of gifts to their home address.

Best Practices for Promoting Holidays to Your Team

Building your employee engagement calendar is just the first step. You must effectively promote the holidays to ensure everyone is adequately prepared and can participate. Here are some best practices to consider:

  • Communicate early: Give your employees ample notice about upcoming engagement holidays so they can plan accordingly. Share an HR calendar at the beginning of the year.
  • Provide equal access to fun: Ensure that your engagement holidays aren’t geared exclusively for your onsite staff or a specific timezone. Thoughtfully consider ways to involve international and remote colleagues.
  • Maintain a holiday calendar: Use a shared calendar or scheduling software to track holidays and time-off requests, making it easy for employees to see when the next company holiday is. Your HR information system (HRIS) can be used to maintain a list of closures and holidays.
  • Involve employees in planning: Foster an environment where team members feel empowered to organize their own engagement holidays. Extend an invitation for suggestions on what should be celebrated. 

Promoting holidays and encouraging work-life balance is essential for maintaining a motivated and engaged workforce. By implementing these best practices, you can create a more supportive and employee-friendly work environment.

Year-Round Activities to Improve Employee Engagement

Employee engagement holidays aren’t your only means of bringing employees together. Smaller, less involved traditions and events can also help boost engagement and morale. Here are some ideas for year-round activities to improve employee engagement:

  • Birthday and anniversary celebrations: Celebrate employees' birthdays and work anniversaries with small parties, decorations, or simple gestures to show appreciation.
  • Employee-led clubs or interest groups: Encourage employees to create and lead clubs or groups based on their interests, like book clubs, sports teams, or hobby enthusiasts. 
  • Work anniversary gifts: Provide small gifts or tokens of appreciation to employees on their work anniversaries. 
  • Social gatherings: Plan regular social events outside of work, such as happy hours, picnics, or holiday parties.
  • Wellness challenges: Organize friendly wellness challenges, such as step-count competitions or healthy eating challenges.
  • Lunch and learns: Host regular "lunch and learn" sessions where employees can learn from their colleagues or external experts.
  • Volunteer opportunities: Organize opportunities for employees to give back to the community through volunteer work.

You don’t need to wait for a holiday to celebrate your team. Activities and traditions like these can help foster engagement and morale in the workplace year-round.

Why Employee Engagement Is So Important

Investing in employee engagement isn’t just a best practice, it’s a prerequisite for your company’s long-term success. Gallup’s engagement research shows that having an engaged workplace:

  • Increases productivity by 14%
  • Increases customer ratings by 10%
  • Increases sales by 18%
  • Increases profitability by 23%

Conversely, Gallup’s research also finds that employee disengagement costs companies $8.8 trillion annually — or about 9% of global GDP. That’s why it’s essential for organizations to deliberately track quantitative and qualitative employee engagement data, including metrics like employee Net Promoter Score (eNPS).

1. Engaged cultures are inclusive and psychologically safe.

Employee engagement and inclusivity are closely connected. Employees who feel valued, respected, and included are more likely to be engaged. Conversely, an inclusive environment enhances engagement by making employees feel connected and appreciated. Company events are a great way to help spark those connections.

In an engaged workplace, there is also a higher level of psychological safety, where employees feel comfortable expressing their opinions, ideas, and concerns without fear of retaliation. This safety is essential for creating an inclusive culture where diverse perspectives are welcomed and considered. A multi-year study on psychological safety’s workplace impact also found that it led to higher levels of employee performance and lower levels of interpersonal conflict.

2. Professional development and engagement are connected.

When companies give employees room to grow, they are rewarded with higher engagement metrics and more creative outputs. Individual contributors may also rely less on management in their daily decision-making, making for more agile teams.

According to one 2023 study on talent mobility, 73% of employees want a better understanding of growth opportunities within their organization. When planning your employee engagement holidays, consider ways to make them educational. For example, ask a recruiting team member to host a lunch and learn to talk through job openings and their required skills. 

3. Prioritizing engagement is critical to employee wellbeing.   

When employees are engaged in their work and feel valued, supported, and fulfilled, their wellbeing improves. Keep a close eye on employees' feelings using Lattice’s employee wellbeing survey template.

In addition to ensuring workloads are manageable, scheduling engagement holidays can break up the monotony of everyday work and help stave off burnout. Unchecked, burnout can impact several aspects of your employee experience, leading to disengagement and low productivity. Burnout may also contribute to attendance issues and emotional exhaustion.

Creating an Employee Engagement Calendar

So you’re sold on the idea of building an employee engagement calendar. Now what? Before putting pen to paper, consider what you want to achieve with your calendar — like improving teamwork, reducing turnover, or boosting engagement scores.

With your goals in mind, don’t forget to solicit input from your employees via a survey, focus group, or one-on-one. Ask them what activities they'd enjoy and find most engaging. Don’t forget to gather input from a diverse selection of employees. Onsite and remote colleagues should also feel equally empowered to share their perspectives.
