* \"Formatting\" units are declined according to the rules of the language\n * in the context of a date. \"Stand-alone\" units are always nominative singular:\n *\n * `format(new Date(2017, 10, 6), 'do LLLL', {locale: cs}) //=> '6. listopad'`\n *\n * `format(new Date(2017, 10, 6), 'do MMMM', {locale: cs}) //=> '6. listopadu'`\n *\n * 2. Any sequence of the identical letters is a pattern, unless it is escaped by\n * the single quote characters (see below).\n * If the sequence is longer than listed in table (e.g. `EEEEEEEEEEE`)\n * the output will be the same as default pattern for this unit, usually\n * the longest one (in case of ISO weekdays, `EEEE`). Default patterns for units\n * are marked with \"2\" in the last column of the table.\n *\n * `format(new Date(2017, 10, 6), 'MMM') //=> 'Nov'`\n *\n * `format(new Date(2017, 10, 6), 'MMMM') //=> 'November'`\n *\n * `format(new Date(2017, 10, 6), 'MMMMM') //=> 'N'`\n *\n * `format(new Date(2017, 10, 6), 'MMMMMM') //=> 'November'`\n *\n * `format(new Date(2017, 10, 6), 'MMMMMMM') //=> 'November'`\n *\n * 3. Some patterns could be unlimited length (such as `yyyyyyyy`).\n * The output will be padded with zeros to match the length of the pattern.\n *\n * `format(new Date(2017, 10, 6), 'yyyyyyyy') //=> '00002017'`\n *\n * 4. `QQQQQ` and `qqqqq` could be not strictly numerical in some locales.\n * These tokens represent the shortest form of the quarter.\n *\n * 5. The main difference between `y` and `u` patterns are B.C. years:\n *\n * | Year | `y` | `u` |\n * |------|-----|-----|\n * | AC 1 | 1 | 1 |\n * | BC 1 | 1 | 0 |\n * | BC 2 | 2 | -1 |\n *\n * Also `yy` always returns the last two digits of a year,\n * while `uu` pads single digit years to 2 characters and returns other years unchanged:\n *\n * | Year | `yy` | `uu` |\n * |------|------|------|\n * | 1 | 01 | 01 |\n * | 14 | 14 | 14 |\n * | 376 | 76 | 376 |\n * | 1453 | 53 | 1453 |\n *\n * The same difference is true for local and ISO week-numbering years (`Y` and `R`),\n * except local week-numbering years are dependent on `options.weekStartsOn`\n * and `options.firstWeekContainsDate` (compare [getISOWeekYear]{@link https://date-fns.org/docs/getISOWeekYear}\n * and [getWeekYear]{@link https://date-fns.org/docs/getWeekYear}).\n *\n * 6. Specific non-location timezones are currently unavailable in `date-fns`,\n * so right now these tokens fall back to GMT timezones.\n *\n * 7. These patterns are not in the Unicode Technical Standard #35:\n * - `i`: ISO day of week\n * - `I`: ISO week of year\n * - `R`: ISO week-numbering year\n * - `t`: seconds timestamp\n * - `T`: milliseconds timestamp\n * - `o`: ordinal number modifier\n * - `P`: long localized date\n * - `p`: long localized time\n *\n * 8. `YY` and `YYYY` tokens represent week-numbering years but they are often confused with years.\n * You should enable `options.useAdditionalWeekYearTokens` to use them. See: https://github.com/date-fns/date-fns/blob/master/docs/unicodeTokens.md\n *\n * 9. `D` and `DD` tokens represent days of the year but they are often confused with days of the month.\n * You should enable `options.useAdditionalDayOfYearTokens` to use them. See: https://github.com/date-fns/date-fns/blob/master/docs/unicodeTokens.md\n *\n * @param {Date|Number} date - the original date\n * @param {String} format - the string of tokens\n * @param {Object} [options] - an object with options.\n * @param {Locale} [options.locale=defaultLocale] - the locale object.

same as \"stand-alone\" units, but are different in some languages.\n * \"Formatting\" units are declined according to the rules of the language\n * in the context of a date. \"Stand-alone\" units are always nominative singular.\n * In `format` function, they will produce different result:\n *\n * `format(new Date(2017, 10, 6), 'do LLLL', {locale: cs}) //=> '6. listopad'`\n *\n * `format(new Date(2017, 10, 6), 'do MMMM', {locale: cs}) //=> '6. listopadu'`\n *\n * `parse` will try to match both formatting and stand-alone units interchangably.\n *\n * 2. Any sequence of the identical letters is a pattern, unless it is escaped by\n * the single quote characters (see below).\n * If the sequence is longer than listed in table:\n * - for numerical units (`yyyyyyyy`) `parse` will try to match a number\n * as wide as the sequence\n * - for text units (`MMMMMMMM`) `parse` will try to match the widest variation of the unit.\n * These variations are marked with \"2\" in the last column of the table.\n *\n * 3. `QQQQQ` and `qqqqq` could be not strictly numerical in some locales.\n * These tokens represent the shortest form of the quarter.\n *\n * 4. The main difference between `y` and `u` patterns are B.C. years:\n *\n * | Year | `y` | `u` |\n * |------|-----|-----|\n * | AC 1 | 1 | 1 |\n * | BC 1 | 1 | 0 |\n * | BC 2 | 2 | -1 |\n *\n * Also `yy` will try to guess the century of two digit year by proximity with `referenceDate`:\n *\n * `parse('50', 'yy', new Date(2018, 0, 1)) //=> Sat Jan 01 2050 00:00:00`\n *\n * `parse('75', 'yy', new Date(2018, 0, 1)) //=> Wed Jan 01 1975 00:00:00`\n *\n * while `uu` will just assign the year as is:\n *\n * `parse('50', 'uu', new Date(2018, 0, 1)) //=> Sat Jan 01 0050 00:00:00`\n *\n * `parse('75', 'uu', new Date(2018, 0, 1)) //=> Tue Jan 01 0075 00:00:00`\n *\n * The same difference is true for local and ISO week-numbering years (`Y` and `R`),\n * except local week-numbering years are dependent on `options.weekStartsOn`\n * and `options.firstWeekContainsDate` (compare [setISOWeekYear]{@link https://date-fns.org/docs/setISOWeekYear}\n * and [setWeekYear]{@link https://date-fns.org/docs/setWeekYear}).\n *\n * 5. These patterns are not in the Unicode Technical Standard #35:\n * - `i`: ISO day of week\n * - `I`: ISO week of year\n * - `R`: ISO week-numbering year\n * - `o`: ordinal number modifier\n * - `P`: long localized date\n * - `p`: long localized time\n *\n * 6. `YY` and `YYYY` tokens represent week-numbering years but they are often confused with years.\n * You should enable `options.useAdditionalWeekYearTokens` to use them. See: https://github.com/date-fns/date-fns/blob/master/docs/unicodeTokens.md\n *\n * 7. `D` and `DD` tokens represent days of the year but they are ofthen confused with days of the month.\n * You should enable `options.useAdditionalDayOfYearTokens` to use them. See: https://github.com/date-fns/date-fns/blob/master/docs/unicodeTokens.md\n *\n * 8. `P+` tokens do not have a defined priority since they are merely aliases to other tokens based\n * on the given locale.\n *\n * using `en-US` locale: `P` => `MM/dd/yyyy`\n * using `en-US` locale: `p` => `hh:mm a`\n * using `pt-BR` locale: `P` => `dd/MM/yyyy`\n * using `pt-BR` locale: `p` => `HH:mm`\n *\n * Values will be assigned to the date in the descending order of its unit's priority.\n * Units of an equal priority overwrite each other in the order of appearance.\n *\n * If no values of higher priority are parsed (e.g. when parsing string 'January 1st' without a year),\n * the values will be taken from 3rd argument `referenceDate` which works as a context of parsing.\n *\n * `referenceDate` must be passed for correct work of the function.\n * If you're not sure which `referenceDate` to supply, create a new instance of Date:\n * `parse('02/11/2014', 'MM/dd/yyyy', new Date())`\n * In this case parsing will be done in the context of the current date.\n * If `referenceDate` is `Invalid Date` or a value not convertible to valid `Date`,\n * then `Invalid Date` will be returned.\n *\n * The result may vary by locale.\n *\n * If `formatString` matches with `dateString` but does not provides tokens, `referenceDate` will be returned.\n *\n * If parsing failed, `Invalid Date` will be returned.\n * Invalid Date is a Date, whose time value is NaN.\n * Time value of Date: http://es5.github.io/#x15.9.1.1\n *\n * @param {String} dateString - the string to parse\n * @param {String} formatString - the string of tokens\n * @param {Date|Number} referenceDate - defines values missing from the parsed dateString\n * @param {Object} [options] - an object with options.\n * @param {Locale} [options.locale=defaultLocale] - the locale object.

week-numbering year tokens `YY` and `YYYY`;\n * see: https://github.com/date-fns/date-fns/blob/master/docs/unicodeTokens.md\n * @param {Boolean} [options.useAdditionalDayOfYearTokens=false] - if true,
