Few events spark as much nostalgia as summer for parents.

Heat waves notwithstanding, camps, vacations, jobs, and time in the neighborhood pool spark fond memories, which ripple into pop songs devoted to the joys of summer.

Yet for many parents from all walks of life, the summer break from school can be simultaneously painful.

That pain is why I argue in my new book, “From Reopen to Reinvent,” that it’s well past time that many more schools began offering year-round schooling. Such a move would not only aid parents, but it would also reduce stress on students and burnout among teachers.

The parental pain stems from many angles.

For some, it’s the agony and pressure of planning and constant coordination.
