Drawing on school bulletins, calendars, and field notes—including a documented inventory of 37 planned special days at one school—the report tallies special days conservatively at 35, with instructional reductions "from 20 to 100 percent."
"This brings our conservative tally of the number of special days to 35, which approaches one-fifth of the school year. Depending on the habits of their teachers and their school, some students may have up to twice this number. Reductions in instructional time on these days range anywhere from 20 to 100 percent."
