First Play Date - Tuesday, August 18. Based on previous years it was anticipated that 1st scrimmage and 1st match dates would be different (August 25 and August 27, respectively). However, the master calendar now has the same date for the first scrimmage and the first match (the first possible play date).
The earlier play date does not change the CIF rules about practices and scrimmages. Each player must have participated in a minimum of five team practices before competing in a scrimmage or a match (Green Book - Article XI, L). Up to a maximum of two scrimmages may be scheduled before any matches are played. Once you have played a match, you may not have a scrimmage (Green Book - Article XI, R, 2).
First legal date for practice is Monday, August 10.
