March 14 – Share it with a Sister
Save the date! Alpha Delta Pi invites you to celebrate March 14, 2026 (aka Pi Day), with a sister, for the fourth annual Alpha Delta Pi Day.
What is Pi Day?

The mathematical symbol for Pi is 3.141529, representing a concept that has no boundaries – much like the infinite bonds of sisters shared with Alpha Delta Pi.
Each year, on March 14, ADPi proudly celebrates Pi Day, a cherished tradition that unites sisters around the world. This special day offers a meaningful opportunity for members to reflect on the profound significance of their ADPi memberships and come together in celebration. It serves as a powerful reminder that despite our differences, the shared legacy of ADPi bonds us all together. ADPi is not just a part of our individual lives but connects us all for a lifetime.
When is Pi Day this year?
This year, ADPi invites you to celebrate Pi Day on Saturday, March 14, 2026. In honor of Alpha Delta Celebrating its 175th Anniversary, our Memorial Headquarters and the newly renovated History Center (located in Atlanta, Georgia) will be hosting a Pi Day open house on Saturday, March 14, 2026.
