School Closings & Delays - School District of Janesville

A 2 hour delay

On a delay morning every school starts 2 hours late.

“If the SDJ decides a 2-hour delay is needed, middle and high school classes will begin at 10:00 AM, with elementary school starting at 10:15 AM. On delay days, school breakfast will not be available, but school lunches will.”
Delay schedule

2 built in snow days

On the 2026 to 2027 calendar, listed as “inclement weather days ('snow days')”.

“The SDJ school calendar has built-in time to accommodate weather delays/closures. With that in mind, the SDJ will allow for two inclement weather days to be just that – 'snow days' on which no school work will be required of students.”

Making up a lost day

Beyond the first two days, the district announces a plan for any missed hours.

“With any additional inclement-weather days beyond the first two, the SDJ will communicate plans to address any missed instructional hours that may need to be made up.”
