What historical event is celebrated annually by Alpha Delta Pi?

Founders' Day is celebrated annually by Alpha Delta Pi to honor the sorority’s establishment and the pioneering women who played a vital role in its creation. This event commemorates the founding members and reflects on the values and legacy they set forth, which continue to guide the organization today. Celebrating Founders' Day allows members to connect with their history, reinforce their commitment to the sorority’s ideals, and inspire future generations of women.

The other choices represent different aspects of a sorority's activities and events. Charter Day often pertains to the date on which a specific chapter was chartered, while Alumni Reunion Day focuses on bringing together former members to celebrate their shared experiences. Service Recognition Night is typically a time to acknowledge members for their contributions to community service and philanthropy rather than a celebration of the organization’s founding. Each of these events has its significance, but they do not carry the same historical importance as Founders' Day for the organization as a whole.
