September 2025 Diversity and Inclusion Calendar: Key Dates
What Employers Need to Know About September 2025 DEI Dates
Labor Day - September 1
Labor Day is a statutory holiday in both Canada and the United States. Its roots trace back to labour movements of the late 19th century, when workers organized for better conditions and recognition. In 1882, labour leader Peter J. McGuire led celebrations in both Toronto and New York City. By 1894, both countries formally recognized the day.
While Labor Day began with activism, it has since become a day of rest and community. Consider using this day to thank your team for their hard work and dedication.
Mawlid - September 4–5
Mawlid al-Nabi marks the birth of the Prophet Muhammad and is one of the most important days in the Islamic calendar. Observances include street carnivals, poetry readings, and shared meals.

A great first step is to read How to Welcome the LGBTQIA+ Community in Your Workplace, which offers actionable insights for creating a supportive environment for all LGBTQIA2+ employees, including those who identify as bisexual.
This resource is especially valuable for HR professionals and team leads looking to deepen their understanding of inclusive language, policies, and practices.

These tools are simple but powerful ways to build a more informed, welcoming, and affirming workplace culture.
