Diversity & Inclusion calendar 2025

You are probably aware of the numerous benefits a diverse and inclusive workplace has on both its employees and the company. Some examples are high employee retention, increased innovation, increased profits and improved employee wellbeing. Despite this, senior roles are 33 times more likely to go to upper-class white men than ethnic minority women. Also, in the United Kingdom, only 25% of tech employees are from ethnic minority groups, with 5% identifying as Black. Therefore, it is essential that we do what we can to increase these numbers.

One way to show your support for diversity and inclusion in the workplace is by celebrating important days. So, we have put together a calendar with noteworthy inclusion dates as well as prominent religious days. However, for an extensive calendar of religious holidays, please see Diversity Resources’ 2025 calendar.
