Updated 2026-09-10 · recomputed on every daily refresh of the 57,975-notice archive.
The WARN Act is a law about a number of days. Every state publishes the notices; none of them publishes the number. So we compute it — for every notice in the archive, back to 1988, every day.

Years with fewer than 50 measurable notices are in the CSV but not shown here; 2026 is still running.
Ten notices dated 1988 or later, ranked by workers affected, where fewer
than 60 days separated the notice from the layoff. Every one of these rows,
with its computed notice_days, is in the free CSV below.

Of 57,975 notices in the archive, 31,720 carry both a notice date and a layoff date on or after it. Those are the only ones counted above. The rest are excluded rather than guessed at:
That exclusion list is the product. A number you cannot audit is worth nothing, and the states' own files are messier than anyone selling a layoff feed will tell you.
Free — 31,720 notices dated 1988 onward, with the
computed notice_days column, as CSV. No account, no email, no rate limit.
Free — the whole-archive summary, 437 state-year rows back to 1988: how many measurable notices each state published each year and how many of them fell under 60 days (notice_period_by_state_year.csv). Aggregate counts only, so it is free at full archive depth. The share column is left blank for any state-year with fewer than 30 measurable notices — a percentage over a handful of records reads as a fact and is not one.
Free — the whole archive, not a sample: all 57,975 notices back to 1988 carry the computed notice_days column, and the 11,888 records with a layoff date before the notice date are flagged rather than dropped, so you can audit them yourself. It is the same file these charts are built from, rebuilt every morning. Nothing here is paywalled; the one paid product is a per-customer daily watch.
Also published as a Hugging Face dataset with a full method card: us-warn-act-layoff-notice-period-days (same rows, rebuilt by the same daily run).

notice_days = effective_date − notice_date in calendar days, computed
per notice from the dates the state published, with no interpolation and no imputation.
Notices are counted by their own notice date, so a year's figure never moves once that
year is complete except when a state back-fills a record. Both dates ship in the
free dataset; this page adds the arithmetic, the exclusions and
the daily rebuild.
This page reports the number of calendar days between the notice date and the layoff date as published by the state. It is not a finding that any employer broke the law and it is not legal advice. The federal WARN Act applies only to covered employers and covered events, and it excuses short notice in defined circumstances — a faltering company seeking capital, business circumstances that were not reasonably foreseeable, and natural disasters. Several states also run their own notice laws with different periods. In several states the published notice date is the day the state received the filing, which can trail the day workers were told by days or weeks — so an interval a little under 60 is often state processing lag, not short notice. A short interval here is a question worth asking, not an answer.
