16 Month Calendar, September 2026 to December 2027

What this page sets up

Sixteen pages, one month each, from September 2026 to December 2027, with the US federal holidays marked and a lined notes column beside every month for lesson plans, grading deadlines and parent-teacher nights. From June on, the page opens on the next September.

A school year and a bit

Teachers plan in terms, not calendar years. A calendar that stops in June leaves nowhere to write next year’s in-service days or the first day back, and one that starts in January splits the school year across two. Sixteen months carries you from the first week of school through summer training and into the first term of the following year, the same span as the teacher planners sold each summer. Print the months you need now and the rest later: every page stands on its own.

Counting the working days

The table under this text gives each of the sixteen months with its weekdays, the federal holidays on a weekday and the working days left. It’s the ceiling for instructional days in a month before your district’s own breaks, so it helps when you pace a unit or schedule testing windows.

Making it a planner

Tick Fillable PDF to type the district’s dates into the day boxes before printing, and punch the pages for a binder. For a single sheet showing the whole school year, open the school year calendar and choose 12 months per page; for a longer span, the 18-month calendar.
