Workplace Diversity, Equity, and Inclusion (DEI) Holiday Calendar for 2024

A good start for incorporating more diverse and inclusive programming and practices into your organization is with a Diversity, Equity, and Inclusion (DEI) calendar.

Celebrating diverse holidays at work is important for creating a fair, inclusive workplace where every team member feels a sense of belonging. Honoring these holidays celebrates the different backgrounds, cultures, and perspectives your team members bring to the table.

A recent survey found that 82% of employees feel more valued when their companies celebrate DEI holidays. Additionally, companies that actively support DEI and acknowledge these holidays have seen a 23% increase in employee retention.

Now that Juneteenth is recognized as a national holiday, many organizations are looking for more ways to support social justice issues and honor their diverse teams.

Celebrating DEI holidays is more than just a nice gesture. It’s a way to make our work environments better for everyone. It not only broadens cultural intelligence, it spotlights your workplace culture and supports employee well-being. It also keeps DEI top of mind throughout the year!

To help you bring opportunities to learn about DEI into your company’s engagement calendar, we put together this inclusive calendar of holidays, observances, and celebrations.

Note: the list isn't exhaustive – there are so many amazing global holidays and events you can choose to honor! This list is a great starting point for HR leaders who want to level up their DEI programming in a way that will be fun and engaging for their teams.

Celebrating employees through recognition or work anniversaries is one of the most powerful ways to keep engagement up and encourage your employees to perform at their best – even in the face of huge changes and struggles.

Studies show that being recognized for a job well done motivates employees to go the extra mile and creates a positive impact across the organization.

Shoutouts for years of service or reward initiatives tied to tasks is a simple way to award standout performance. Platforms like Cooleaf can help keep employee engagement high and burnout levels low.

“Cooleaf gave our people the opportunity to appreciate others they’ve worked with on a daily basis but never saw in person,” Kiley Skadburg, Chief Marketing Officer at the Iowa Clinic told Cooleaf co-founder John Duisberg during an episode of The Great Retention podcast.

“They can now say ‘Thank you for helping me get that patient in’ or ‘Thank you for going above and beyond and staying late’ and that was the amazing part about it. From a cultural perspective, it created space for people to connect and see the interactions happening on the feed.”

Deciding Which Holidays to Observe

With so many diversity and inclusion events and religious observances, it can be a challenge to determine which ones to observe. Why not get your employees involved to build a meaningful calendar together?

You can do this by leveraging your ERGs, building a task force, or sending out a quick pulse survey.

Involving your employees in the decision-making process shows that you genuinely care about their perspectives and want to create an inclusive environment. This way, the holidays you choose to observe will truly reflect the values of diversity and inclusivity in your workplace!

Example Programming for DEI Holidays

So how do you bring DEI into your engagement programming? The calendar is a great jumping-off point. Cooleaf also offers DEI programming to help you foster a more inclusive culture that meets your organization’s goals. Scroll down for ideas to start!

May - Cinco De Mayo

Cinco de Mayo is widely celebrated in the U.S., but the holiday’s origins are often misunderstood.

In Mexico, Cinco de Mayo is a celebration of the first battle of Puebla, when the Mexican Army successfully defended the city against invading French forces in 1862. Cinco de Mayo is commonly mistaken as Mexican Independence Day, which is in September.

To celebrate this holiday, we encouraged employees to learn more about the real history of Cinco de Mayo.

July - Nelson Mandela International Day

Nelson Mandela International Day celebrates the legacy of the former President of South Africa and anti-apartheid revolutionary, who shined an immense light on the world.

Celebrated annually on his birthday July 18, Nelson Mandela International Day is a global call to action that celebrates the belief that every individual is capable of transforming the world. The United Nations also provides Mandela’s previous speeches to empower others.

For this holiday, we challenged employees to consider their beliefs about making an impact. In the example below, employees used the Cooleaf platform to connect with one another and share how they define commitment to social purpose.

Encourage positive impact through creative social responsibility challenges

Additionally, simply taking the time to share information and resources about diverse national events in your communication channel of choice (such as Slack or Microsoft Teams) can be a great way to start a conversation and bring DEI into daily work life!

Cooleaf can help organize creative events, communications, and education for your DEI strategy. Want to learn more? Talk to us!
