    "incantation": "When computing a date with a negative weekday offset, use the `weekday -N` modifier. It moves backward to the most recent previous date with that weekday; `N` must be an integer from -6 through 0.",

      "SELECT date('<time-value>', 'weekday -<N>');"
    ],
    "gotchas": [
      "Version: 3.54.0",
      "time-value (required): Date/time input; date/time functions accept ISO-8601 text or Julian day numbers, and Unix timestamps when followed by `auto` or `unixepoch`.",
      "weekday -N (required): Weekday modifier: negative N moves backward to the most recent previous weekday. N must be an integer from -6 to +6; if already on that weekday, the date is unchanged.",
      "date() (required): Returns the resulting date as text in `YYYY-MM-DD` format.",
      "Prerequisite: Negative weekday values are supported beginning with SQLite 3.54.0."
