Validate an exported job schedule against local operating hours, holidays, deadlines, and required upstream jobs. It reads local documents, expands bounded real UTC minutes through an explicit IANA time zone, and never starts or changes a job.

This walkthrough uses the tool's public README and checked-in example files. Run the command from a repository checkout with Node.js 22+.

Run the checked-in example

node bin/schedule-window-validator.mjs --root examples --schedule passing.json --policy policy.json
node bin/schedule-window-validator.mjs --root examples --schedule failing.json --policy policy.json --human
npm run check

--root declares the evidence directory. --schedule and --policy are relative paths within it. Optional --out report.json writes a copy of stdout inside that root after alias and symlink checks. JSON always goes to stdout; --human adds a brief summary to stderr. --help lists options.
