In general the recreation league has two events each week - two practices, two games, or a game and a practice. This is on average however, and any single week may have more or less, especially near the end of the season if many rainouts need to be made up.
Tee Ball and International Leagues will play any day of the week, though Sundays are generally avoided unless used for a make up game.
The competitive leagues (National, American, and Teen) will play on all but Wednesdays, Sundays, and Saturday afternoons as these are set aside for the travel team program. Coaches may request practice times on any day of the week, but they are advised to avoid these times.
