OA BIRTHDAY
The third full weekend (Friday included) of January has been set aside as the annual celebration of the January 19, 1960 founding of Overeaters Anonymous.
UNITY DAY
Unity Day is a day to celebrate the connection of all members and groups of OA to one another.
It occurs the last Saturday in February in even years and the last Sunday in February in odd years at 11:30 a.m. local time. Unity Day was created to reaffirm the love and understanding shared by members of our Fellowship—with an emphasis on Tradition One: “Our common welfare should come first; personal recovery depends on OA unity.” It is encouraged that all members of OA take a moment of silence to express their gratitude for the OA Program.
Within GPIOA, it has traditionally been observed with an event that includes a group recitation of "Roseanne's Prayer" (also known as "The OA Promise" or "I Put My Hand in Yours...":
I put my hand in yours, and together we can do what we could never do alone. No longer is there a sense of hopelessness, no longer must we each depend upon our own unsteady willpower. We are all together now, reaching out our hands for power and strength greater than ours, and as we join hands, we find love and understanding beyond our wildest dreams.
SPONSORSHIP DAY
Celebrated the third full weekend (Friday included) of August, this is a day set aside to acknowledge the importance of sponsoring in our Fellowship.
INTERNATIONAL DAY OF EXPERIENCING ABSTINENCE (IDEA)
International Day of Experiencing Abstinence (IDEA), celebrated the third full weekend (Friday included) in November, encourages OA members worldwide to begin or reaffirm their abstinence from compulsive overeating.
12TH STEP WITHIN DAY
December 12 (12/12) each year is designated as OA’s International Twelfth Step Within Day. The purpose is to encourage OA service bodies, meetings, and individual members to reach out to those within the Fellowship who are still suffering from compulsive eating behaviors.
