Jeffco Calendar 2026-27: Winter Break Dec. 21-Jan. 5, Last Day May 27

Jeffco Public Schools has no school for students from Monday, Dec. 21, 2026 through Tuesday, Jan. 5, 2027, and the last day of school for all students is Thursday, May 27, 2027, according to the district’s “District Family Calendar 2026-2027.” On May 27 every district school dismisses 2.5 hours earlier than the regular time. The story lists every no-school weekday, the three potential snow make-up days, the student-day counts and the 2027-28 dates already posted, plus a printable school-year calendar.

Jeffco breaks and no-school days in 2026-27

The PDF lists breaks, legal holidays and staff development days in separate blocks. The table puts every weekday off for students in date order. Weekdays and counts are our arithmetic from the district’s dates; the district’s wording is in quotes. Days with an asterisk are the three “Potential Snow Make Up Days.”

Dates	Weekdays off	What the calendar calls it
Mon., Sept. 7, 2026	1	“Labor Day” (legal holiday)
Fri., Sept. 18, 2026	1	Teacher staff development day
Mon.-Tue., Oct. 12-13, 2026	2	“Fall Break”
Mon.-Fri., Nov. 23-27, 2026	5	“Thanksgiving Break”
Mon., Dec. 21, 2026 to Tue., Jan. 5, 2027	12	“Winter Break”; Jan. 4 and 5 are also staff development days
Mon., Jan. 18, 2027	1	“Martin Luther King” (legal holiday)
Fri., Feb. 12, 2027*	1	Staff development day, potential snow make-up
Mon., Feb. 15, 2027	1	“Presidents’ Day” (legal holiday)
Mon.-Fri., March 22-26, 2027	5	“Spring Break”
Mon., March 29, 2027*	1	Staff development day, potential snow make-up
Fri., April 30, 2027*	1	Listed under “No School for Students,” potential snow make-up

That is 31 weekdays, 28 without the three asterisked days. Memorial Day (May 31) and Juneteenth (observed June 18) are legal holidays too, but both come after the last day of school. Veterans Day, Wednesday, Nov. 11, is not on the calendar’s lists of days off. Put the next break on the December 2026 calendar.

When does Jeffco winter break start and end?

Winter break runs “Dec. 21-Jan 5,” from Monday, Dec. 21, 2026 to Tuesday, Jan. 5, 2027. Christmas Day (Dec. 25) and New Year’s Day (Jan. 1) are listed legal holidays inside it. The calendar prints no first day back. Wednesday, Jan. 6 is the first weekday it does not mark off, which is our reading.

The break is the longest on the calendar. Counting the weekends on both sides, students are out from Saturday, Dec. 19 through Tuesday, Jan. 5, 18 days. Denver Public Schools lists winter break as Dec. 21 to Jan. 1 with a planning day on Jan. 4 and a first class day of Jan. 5, per our Denver Public Schools calendar story, so Jeffco’s first day back is one day later. Douglas County School District lists Dec. 21-31, per our Douglas County story. The winter break 2026 roundup compares more districts.

When is Jeffco spring break 2027?

Monday, March 22 to Friday, March 26, 2027, “Spring Break: March 22-26.” Monday, March 29 is a staff development day and one of the potential snow make-up days. If the district does not use it, the week off is followed by one more day without students. Spring break in Denver is March 29 to April 2 and in Douglas County March 15-19, each per its own story, so Jeffco’s week falls between the two. See the week on the March 2027 calendar.

What are the Jeffco snow make-up days?

The calendar lists “Potential Snow Make Up Days” on Feb. 12, March 29 and April 30, 2027, each marked with an asterisk. Feb. 12 and March 29 are teacher staff development days; April 30 sits in the “No School for Students” list. So two of the three replace a day when only teachers work, and one replaces a day off for everyone.

Our arithmetic shows how they are counted. There are 202 weekdays from Aug. 19, 2026 to May 27, 2027. Take away the 31 weekdays in the table and 171 remain, the same as the district’s 79 student contact days in the first semester plus 92 in the second. That total counts the three potential snow days as days off. The calendar adds that “additional modified contact days will be identified on individual school calendars.”

What happens on May 27, the last day of school?

Thursday, May 27, 2027 is the “Last Day of School for All Students.” The calendar says “all PK-12 district schools dismiss 2.5 hours earlier than regular dismissal time.” Charter schools are the exception to that note: “This schedule does not apply to charter schools,” and charter families should contact their schools about May 27 dismissal times. Friday, May 28 is a staff development day and summer break runs May 28 to June 30.

When did the Jeffco school year start, and what is left?

All students started Wednesday, Aug. 19, 2026, per the calendar’s “First Day of School for All Students.” Teacher staff development days were Aug. 11-14, 17 and 18. Kindergarten and preschool start dates are not printed on the family calendar, and neither is a Board approval date; its footer is dated 5/22/26. The next day without students is Monday, Nov. 23, the first day of Thanksgiving break; Thanksgiving Day is Nov. 26. The district lists 87 teacher workdays in the first semester and 98 in the second.
