Interim Meeting conducts the business of Philadelphia Yearly Meeting between annual sessions.
The basic structure, functions, and responsibilities of Interim Meeting are outlined in Faith and Practice. Meetings are held on the second Saturday of January, February, April, May, October and November at the Arch Street Meeting House.
Most members of Interim Meeting are appointed by the PYM monthly meetings, with three at-large members appointed by the yearly meeting plus several ex-officio members. All Interim Meetings are open to Friends and attenders of Philadelphia Yearly Meeting and visitors from other Quaker bodies.
