Calculate the number of school days (weekdays) between two dates in a term.
Pick both dates to see the count.
This tool counts weekdays (Monday-Friday) between a term's start and end date -- the same underlying calculation as the Working Days Calculator, applied to planning a school term, semester, or academic calendar.
Pick your term's start date and end date. The number of school days (weekdays) appears instantly.
The tool goes through every calendar date from your term start to your term end and counts those that fall on Monday through Friday. Both the first and last dates are included, and if you enter them in the wrong order the tool swaps them. It performs no lookup of school calendars, so it does not know about holidays, teacher training days, exam study leave, snow days or half days. The number it returns is the count of weekdays that fall within the term window, which is an upper limit on the number of instruction days rather than a prediction of them.
Suppose, hypothetically, a term starts on a Monday and ends on a Friday exactly twelve weeks later. Twelve full weeks contain 12 x 5 = 60 weekdays. Now assume the school closes for one mid-term week and observes two single-day holidays that fall on weekdays. Subtract 5 for the break and 2 for the holidays: 60 - 5 - 2 = 53 instructional days. If the term ended on a Wednesday instead, the count would be 58 before adjustments, because the final week only contributes Monday to Wednesday. The exact adjustments must come from your own school's published calendar.
For scheduling weekly classes, it can help to divide the weekday count by five to get an approximate number of school weeks, then round down if the term starts or ends midweek. A count that is not a multiple of five tells you that the first or last week is partial. That partial week matters when a subject meets on only one day of the week, since it may occur one time fewer than the rest.
This is a planning aid. Do not use it as evidence for attendance disputes, funding claims or regulatory reporting. For those purposes rely on the official school calendar or records kept by your school or local authority.
No -- it counts every weekday in the range. If your term includes a mid-term break, subtract those weekdays manually from the result.
Yes, if they fall on a weekday. Both boundary dates are included in the total.
The tool counts every Monday to Friday date, so it includes holidays, in-service days and breaks. Subtract those from the result using your school's official calendar.
Divide the weekday count by 5. A whole number means the term covers complete weeks, while a remainder means one or both end weeks are partial.
Yes. Run each term separately with its own start and end dates and add the totals. That skips the breaks between terms without any manual subtraction.
