What's in the library
PlannerGrid currently publishes 242 printable templates across 8 categories. Every template is a real, full HTML page — not a thumbnail linking off-site, not a download gate, not a paywall. Open the page, hit print, and the layout drops cleanly onto US Letter paper.
The categories cover the full sweep of the school year: full academic-year calendars, semester schedules, teacher lesson and gradebook planners, student daily and weekly layouts, homeschool planning grids, subject-specific trackers, specialty templates (reading logs, behavior charts, IEP trackers), and a growing set of district and university calendars from major U.S. systems.
How the data is built
Each template is generated from a structured seed. The seed reads from two sources:
- U.S. federal holiday list — the canonical eleven federal holidays as designated by the U.S. Office of Personnel Management. These are overlaid on every academic-year and semester calendar so observed days never collide with planned instruction.
- U.S. K-12 and university scheduling conventions — standard term lengths, semester boundaries, quarter and trimester divisions, common holiday weeks (Thanksgiving, winter break, spring break), and the typical August or September start dates used by major U.S. school systems.
The seed script attempts a live fetch from each upstream source first; when an upstream source is unreachable, it falls back to a curated snapshot of the same data shipped with the build. The current data source on this build is: Live OPM federal holiday page + curated U.S. K-12 / university scheduling conventions.
OPM federal holiday page reachable at build time; canonical 11-holiday list used and overlaid on every academic-year and semester template. K-12 district and university calendar patterns from curated long-running scheduling conventions.
Why August-to-July
The August-to-July cycle is the academic year used by the vast majority of U.S. K-12 districts and the dominant pattern at four-year universities (which start in late August or early September and close out in May or June). Planning calendar-year-first means a teacher's annual planner expires in the middle of the spring semester. Planning year-first means the planner ends with the last day of school — the way teachers actually think about time.
Templates as full HTML pages
Every template renders as server-side HTML. There is no JavaScript framework involved in viewing a planner — just a PHP page that pulls structured content from the seed and writes it out. That means the templates are crawlable, archivable, printable from any browser, and accessible to screen readers without special handling. It also means you can open this site on a school computer behind a strict content filter and the pages will still render.
Free for teachers, students, and homeschoolers
PlannerGrid is free to use for personal, classroom, and homeschool printing. You can save pages locally, share with colleagues, distribute photocopies to a class, or build classroom binders without attribution. We ask only that you don't repackage and resell the templates as a paid product.
