The Annual Meeting of The Society of Rheology is held in mid-October. The meetings ordinarily last three to four days and are open to both members and non-members. Every effort is made to stimulate and encourage fruitful discussion during the technical sessions, with 25 minutes normally allotted to the presentation and discussion of each paper. There are normally no more than four simultaneous sessions, and the program includes plenary lectures, special symposia, informal evening discussions, and instrument exhibits.
