How we build it

Every date, sourced

Board-adopted calendars, district PDFs and portals — collected, parsed, and reconciled against NCES records.

Scored

Confidence on every row

A 0–1 score tells you which dates are verified from source versus inferred, so you can filter to your threshold.

Joinable

NCES IDs, everywhere

Standard identifiers on each district — join straight onto Census, enrollment, or your own geodata.

Fresh

Reconciled daily

Calendars change. We re-check sources every day and version the diffs so your features never go stale.

Honest coverage

40% of districts have a confirmed 2026–27 calendar today — we’re collecting the rest now, and every estimated date is labeled as such on the page. Earlier years run 76–84% confirmed. We’d rather show you a gap than paper over it.

Who uses this

School schedules are one of the strongest demand signals in America.

When 46 million kids go on break, families move. Parks fill, flights book, hotels surge. We turn the raw calendar into a clean, joinable feature — no scraping, no PDF parsing, no guessing which of a state's 900 districts start early.

The data is the product

One request. Every district's year.
