How to use the school days calculator
Set the dates

See the school days left, the weeks of school left and a month-by-month table.
How school days are counted
The calculator counts every school day from the first date to the last date, with both dates included. Saturdays and Sundays are skipped, and Fridays are skipped too for a four-day week. Then it subtracts the days off you entered.
School days formula
Weekdays = school-week days from the first date to the last date, both included
School days left = weekdays − holidays and break days
Weeks left = school days ÷ school days per week
The tool cannot know your district calendar, so add holidays and breaks yourself.
School days examples
Example 1: the rest of the school year
From November 7, 2026 to June 10, 2027, with 25 weekdays off for holidays and breaks.
- Weekdays in the period 154
- Minus holidays and breaks 25
- School days left 129
- Weeks of school left 25 weeks and 4 days
About 129 school days remain, which is just over 25 school weeks.
Example 2: one school week
Monday, November 9 to Friday, November 13, 2026.
- Five-day week 5 school days
- With 1 holiday 4 school days
- Four-day week (Mon–Thu) 4 school days
A single day off, or a four-day week, takes the week from 5 days to 4.
Example 3: a weekend only
Saturday, November 7 to Sunday, November 8, 2026.
- School days
Saturday and Sunday are never counted as school days.
School days and school weeks
A five-day week turns school days into weeks.
- 180 school days 36 weeks
- 170 school days 34 weeks
- 160 school days 32 weeks
Divide any number of school days by 5 to get weeks. A four-day week divides by 4.
