The count is exclusive of the start date and inclusive of the end date: day one is September 1, 2025 plus 24 hours. Weekends and public holidays are included — for working days only, use the business days calculator.
A typical American school year running from early September to mid-June spans about 287 days end to end, of which roughly 180 are instructional days once weekends, winter break, and spring break are removed. Districts vary, but this is the common shape of the calendar.
Method & sources
Day counts use the Gregorian calendar and are computed on calendar dates in UTC, so daylight-saving changes never add or remove a day. The count excludes the start date and includes the end date — the same convention as subtracting one date from another.
