School-Day Calculator
This tool estimates school-day deadlines for special education timelines using district calendars.
About This Tool
This calculator helps educators and evaluators estimate special education timelines using published school calendars.
School-day deadlines can be difficult to calculate due to weekends, holidays, and district-specific non-instructional days. This tool is designed to simplify that process by using verified calendar data and consistent counting rules.
While the calculator is built for accuracy, users should always confirm deadlines with official district policies.
