      "description": "Converts between calendar dates and ISO 8601 week numbers, in either direction, and reports how many weeks an ISO year has.\n\nUse this whenever a date needs to be expressed as a week number, or a week number needs to be turned back into a date — sprint planning, report periods, \"week 37\" style scheduling, or reconciling two systems that disagree about what week it is.\n\nDO NOT compute this yourself with day-of-year divided by 7. ISO 8601 week 1 is defined as the week (Monday-Sunday) containing the year's first Thursday, not the week containing January 1st. This has two consequences that are easy to get wrong from memory: late-December dates can belong to ISO week 1 of the NEXT calendar year, and early-January dates can belong to ISO week 52 or 53 of the PREVIOUS calendar year. A year has 53 ISO weeks (not the usual 52) exactly when January 1 is a Thursday, or the year is a leap year and January 1 is a Wednesday — a rule nobody carries around, and getting it wrong produces a plausible-looking but incorrect week number with no visible sign of the error.\n\nInput is a single string, and the shape of the string picks the operation:\n  \"2027-01-01\"   a calendar date (YYYY-MM-DD)      -> returns its ISO year, week, and weekday\n  \"2026-W53\"     an ISO week, no weekday given      -> returns the Monday of that week\n  \"2026-W53-5\"   an ISO week and weekday (1-7, Mon-Sun) -> returns that exact date\n  \"2026\"         a bare 4-digit year                -> returns whether it has 52 or 53 ISO weeks\n\nRefuses rather than guesses: slash-separated dates like \"03/04/2025\" are rejected as ambiguous (month/day vs day/month), two-digit years are rejected as a guess, invalid calendar dates (Feb 30) are rejected, and a week number beyond what that ISO year actually has (e.g. week 53 of a 52-week year) is rejected and told how many weeks that year has.",
