When my son played, summer league started in May and wrapped up early July.

For any parent of a MCPS student who did summer league, when did it start?
I’ve been told the end of June from one person but they weren’t sure.
Rising son will be going into 9th grade and trying out for the summer league. Also trying to plan a vacation as soon as school is over and be back last week of June so seeing how that will work with timing.
Thanks
