A 2023-2024 calendar to support an inclusive College of Engineering community

Mission statement

The UW College of Engineering is committed to diversity, equity and inclusion. Fostering a positive diversity climate is critical to achieving its benefits and is rooted in understanding how the College influences psychological safety and a sense of belonging for all its constituents. Culture is one of the overarching pillars we pursue in our vision and commitment to building an inclusive and equitable community for all students, staff, faculty and community members. This calendar aims to acknowledge and increase understanding of diverse cultures, traditions, values and beliefs.

Why these dates?

The cultural holidays, observances and events on this calendar were identified based on the following criteria:

  1. A faculty/staff member or student observing this event may be out of the office or absent from class on this day.
  2. A faculty/staff member or student’s engagement level may be affected by rituals practiced in observance of this event (e.g., reduced energy from fasting for Ramadan or negative association with a dominant culture’s holiday, such as Thanksgiving).
  3. A faculty/staff member may not be able to participate in activities before, during or after regular business hours on this day (e.g., not participating in Halloween activities or passing on events happening on the evening of a holy day observed by the Muslim or Jewish communities).
  4. This occasion may provide an opportunity to increase dialogue and knowledge about cultural traditions, celebrations,  historical oppression, resilience, perseverance or triumph that might not otherwise present itself.


This calendar was adapted from a Cultures Connecting resource (Cultures Connecting, 2021), designed to support anti-bias efforts in organizations.

Cultures Connecting. (2021) Cultures Connecting Diversity Calendar 2021-2022 [Online Pamphlet].
