The Los Angeles Unified School District Board of Education voted 4-3 on Tuesday to keep the mid-August start date for the next three years.
The district has used the basic calendar structure with the mid-August start date since the 2012-13 school year.
Some parents had been pushing for a September start to allow more time for summer programs and family vacations.
"In approving calendars through 2020-21 instead of for a single year, board members said they hoped to provide stability by allowing families and employees to plan activities well in advance," the district said in a statement.
The board followed the recommendations of district staff in approving the following calendars:
2018-19:
First semester -- Aug. 14 to Dec. 14
Second semester -- Jan. 7 to June 7
Winter recess -- Dec. 17 to Jan. 4
Spring recess -- April 15 to 19
2019-20:
First semester -- Aug. 20 to Dec. 20
Second semester -- Jan. 13 to June 12
Winter recess -- Dec. 23 to Jan. 10
Spring recess -- April 6 to 10
2020-2021:
First semester -- Aug. 18 to Dec. 18
Second semester -- Jan. 11 to June 10
Winter recess -- Dec. 21 to Jan. 8
Spring recess -- March 26 to March 30
Charter schools, which enroll about 19 percent of district students, will continue to set their own calendars.
