Fractional weeks are\n * truncated towards zero by default.\n *\n * One \"full week\" is the distance between a local time in one day to the same\n * local time 7 days earlier or later. A full week can sometimes be less than\n * or more than 7*24 hours if a daylight savings change happens between two dates.\n *\n * To ignore DST and only measure exact 7*24-hour periods, use this instead:\n * `Math.trunc(differenceInHours(dateLeft, dateRight)/(7*24))|0`.\n *\n * @typeParam DateType - The `Date` type, the function operates on. Gets inferred from passed arguments. Allows to use extensions like [`UTCDate`](https://github.com/date-fns/utc).\n *\n * @param dateLeft - The later date\n * @param dateRight - The earlier date\n * @param options - An object with options\n *\n * @returns The number of full weeks\n *\n * @example\n * // How many full weeks are between 5 July 2014 and 20 July 2014?\n * const result = differenceInWeeks(new Date(2014, 6, 20), new Date(2014, 6, 5))\n * //=> 2\n *\n * @example\n * // How many full weeks are between\n * // 1 March 2020 0:00 and 6 June 2020 0:00 ?\n * // Note: because local time is used, the\n * // result will always be 8 weeks (54 days),\n * // even if DST starts and the period has\n * // only 54*24-1 hours.\n * const result = differenceInWeeks(\n *   new Date(2020, 5, 1),\n *   new Date(2020, 2, 6)\n * )\n * //=> 8\n */\nexport function differenceInWeeks(dateLeft, dateRight, options) {\n  const diff = differenceInDays(dateLeft, dateRight) / 7;\n  return getRoundingMethod(options?.roundingMethod)(diff);\n}\n\n// Fallback for modularized imports:\nexport default differenceInWeeks;","map":null,"metadata":{},"sourceType":"module","externalDependencies":[]}
