TL;DR
Year and term dates define the calendar's working range. Check them before adjusting individual days.
Steps
In Insights, select the school year and open General.
With administrator access, edit Availability dates. Check the start and end of the year and any separate teacher or student access dates.
Save, then open Calendar → Terms to review each term against the school’s approved calendar.
Save term changes and check representative schedules near each boundary.
Changing dates can affect which periods and reports are available. It does not automatically resolve every special-day or section-schedule rule. If dates come from a school integration, coordinate the change in that source.
