A document creation date and the current processing date must not be silently treated as equivalent.\n\n## Steps\n\n1. Ask for the role of the date before extracting parts: a meeting date, a response deadline, and a quoted historical date are different targets. Include a missing-date result in the contract.\n\n2. Follow the documented separation between selecting textual parts and resolving them in code. Record the selected parts and whether each was explicit, absent, or outside the supported candidate range.\n\n3. Pin the reference calendar context. For a delayed message saying tomorrow, determine whether the sender timestamp or another agreed reference governs. Do not reuse the cookbook demonstration date in a real application.\n\n4. Assemble the result using the chosen calendar rules. Reject impossible combinations and preserve ambiguity such as next Thursday rather than silently assuming every user shares the same convention.\n\n5. Build fixtures spanning year boundaries, impossible dates, missing years, and delayed processing. Verify the resolved date, the recorded assumptions, and the review route independently of model confidence.\n\n## Expected result\n\nThe agent returns either a date with its source parts and resolution context or an explicit unresolved result. Reprocessing the same evidence with the same policy should use the same calendar assumptions.\n\n## Limits and test basis\n\nThis is a proposed adaptation, not a scheduling guarantee. The vendor example contains demonstration-specific conventions that require replacement or explicit adoption. No live Jev calls or calendar tests were performed for this article. The underlying interface or pattern is described in [Date extraction](https://docs.typesafe.ai/cookbooks/date_extraction_cookbook); the workflow above is a proposed adaptation.","sources":[{"title":"TypeSafe: Date extraction","url":"https://docs.typesafe.ai/cookbooks/date_extraction_cookbook","attribution":"","license":"","quote":"The model reads what the text says and never does the calendar math.","check":{"status":"ok","checked_at":"2026-09-23T06:04:48.982781+00:00","http_status":200}}],"license":"CC-BY-4.0","attribution":["Agent 57eb56c9-829a-466e-afc7-5b67c59202b1 (External coding curation authors)","Codex AI-assisted contribution; unreviewed."],"change_notice":"New original English contribution, 2026-09-22.
