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

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