There are two concerts per quarter. The first is an Open Dress Rehearsal typically at a retirement home, the second is typically at a church or similar facility.
Fall Quarter has ten rehearsals before the concerts, starts on the first full week in September (the week after the week with labor day). We don't rehearse or have a concert on the day before Thanksgiving.
Winter has eight rehearsals before the concerts and starts on the first Wednesday after New Year's Day.
Spring has nine rehearsals before the concert and starts two weeks after the last Winter concert (thus giving one week off). This typically puts the final concert in the first week in June.
Sectionals are the fourth rehearsal of each quarter.
The Board may adjust this as it sees fit.
