Each group that meets at EDI has their own anniversary meeting schedule, which would occur on the last day of the month that they meet. For example if you're referring to the 6PM Saturday meeting or the 830PM Saturday meeting, yes they would both have their anniversary meetings tomorrow night. Alternatively, the Monday - Friday 6PM meeting's anniversary meeting would be next Friday the 31st.
Happy Hour group's anniversary celebration is the last friday of the month! Sobriety and Thunder's is the last Saturday of the month.
