* - `i` is ISO day of week. For `i` and `ii` is returns numeric ISO week days,
* i.e. 7 for Sunday, 1 for Monday, etc.
* - `I` is ISO week of year, as opposed to `w` which is local week of year.
* - `R` is ISO week-numbering year, as opposed to `Y` which is local week-numbering year.
* `R` is supposed to be used in conjunction with `I` and `i`
* for universal ISO week-numbering date, whereas
* `Y` is supposed to be used in conjunction with `w` and `e`
* for week-numbering date specific to the locale.
* - `P` is long localized date format
* - `p` is long localized time format

* 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://git.io/fxCyr
*
* 9. `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://git.io/fxCyr
*
* ### v2.0.0 breaking changes:
*
* - [Changes that are common for the whole library](https://github.com/date-fns/date-fns/blob/master/docs/upgradeGuide.md#Common-Changes).
*
* - The second argument is now required for the sake of explicitness.
*
* ```javascript
* // Before v2.0.0
* format(new Date(2016, 0, 1))
*
* // v2.0.0 onward
* format(new Date(2016, 0, 1), "yyyy-MM-dd'T'HH:mm:ss.SSSxxx")
* ```
*
* - New format string API for `format` function
* which is based on [Unicode Technical Standard #35](https://www.unicode.org/reports/tr35/tr35-dates.html#Date_Field_Symbol_Table).
* See [this post](https://blog.date-fns.org/post/unicode-tokens-in-date-fns-v2-sreatyki91jg) for more details.
*
* - Characters are now escaped using single quote symbols (`'`) instead of square brackets.
*
* @param {Date|Number} date - the original date
* @param {String} format - the string of tokens
* @param {Object} [options] - an object with options.

* @param {0|1|2|3|4|5|6} [options.weekStartsOn=0] - the index of the first day of the week (0 - Sunday)
* @param {Number} [options.firstWeekContainsDate=1] - the day of January, which is
* @param {Boolean} [options.useAdditionalWeekYearTokens=false] - if true, allows usage of the week-numbering year tokens `YY` and `YYYY`;

* - `i` is ISO day of week. For `i` and `ii` is returns numeric ISO week days,
* i.e. 7 for Sunday, 1 for Monday, etc.
* - `I` is ISO week of year, as opposed to `w` which is local week of year.
* - `R` is ISO week-numbering year, as opposed to `Y` which is local week-numbering year.
* `R` is supposed to be used in conjunction with `I` and `i`
* for universal ISO week-numbering date, whereas
* `Y` is supposed to be used in conjunction with `w` and `e`
* for week-numbering date specific to the locale.

* @name parse
* @category Common Helpers
* @summary Parse the date.
*
* @description
* Return the date parsed from string using the given format string.
*
* > ⚠️ Please note that the `format` tokens differ from Moment.js and other libraries.
* > See: https://git.io/fxCyr
*
* The characters in the format string wrapped between two single quotes characters (') are escaped.
* Two single quotes in a row, whether inside or outside a quoted sequence, represent a 'real' single quote.
*
* Format of the format string is based on Unicode Technical Standard #35:
* https://www.unicode.org/reports/tr35/tr35-dates.html#Date_Field_Symbol_Table
* with a few additions (see note 5 below the table).
*
* Not all tokens are compatible. Combinations that don't make sense or could lead to bugs are prohibited
* and will throw `RangeError`. For example usage of 24-hour format token with AM/PM token will throw an exception:
*
* ```javascript
* parse('23 AM', 'HH a', new Date())
* //=> RangeError: The format string mustn't contain `HH` and `a` at the same time
* ```
*
* See the compatibility table: https://docs.google.com/spreadsheets/d/e/2PACX-1vQOPU3xUhplll6dyoMmVUXHKl_8CRDs6_ueLmex3SoqwhuolkuN3O05l4rqx5h1dKX8eb46Ul-CCSrq/pubhtml?gid=0&single=true

* 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.
* 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://git.io/fxCyr
*
* 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://git.io/fxCyr
*
* 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
*
* ### v2.0.0 breaking changes:
*
* - [Changes that are common for the whole library](https://github.com/date-fns/date-fns/blob/master/docs/upgradeGuide.md#Common-Changes).
*
* - Old `parse` was renamed to `toDate`.
* Now `parse` is a new function which parses a string using a provided format.
*
* ```javascript
* // Before v2.0.0
* parse('2016-01-01')
*
* // v2.0.0 onward (toDate no longer accepts a string)
* toDate(1392098430000) // Unix to timestamp
* toDate(new Date(2014, 1, 11, 11, 30, 30)) // Cloning the date
* parse('2016-01-01', 'yyyy-MM-dd', new Date())
* ```
*
* @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. See [Locale]{@link https://date-fns.org/docs/Locale}
* @param {0|1|2|3|4|5|6} [options.weekStartsOn=0] - the index of the first day of the week (0 - Sunday)
* @param {1|2|3|4|5|6|7} [options.firstWeekContainsDate=1] - the day of January, which is always in the first week of the year
* @param {Boolean} [options.useAdditionalWeekYearTokens=false] - if true, allows usage of the week-numbering year tokens `YY` and `YYYY`;
* see: https://git.io/fxCyr
* @param {Boolean} [options.useAdditionalDayOfYearTokens=false] - if true, allows usage of the day of year tokens `D` and `DD`;

* @throws {RangeError} `options.locale` must contain `match` property
* @throws {RangeError} use `yyyy` instead of `YYYY` for formatting years using [format provided] to the input [input provided]; see: https://git.io/fxCyr

* // Parse 11 February 2014 from middle-endian format:
* var result = parse('02/11/2014', 'MM/dd/yyyy', new Date())
* //=> Tue Feb 11 2014 00:00:00
*
* @example
* // Parse 28th of February in Esperanto locale in the context of 2010 year:
* import eo from 'date-fns/locale/eo'
* var result = parse('28-a de februaro', "do 'de' MMMM", new Date(2010, 0, 1), {

*
* - [Changes that are common for the whole library](https://github.com/date-fns/date-fns/blob/master/docs/upgradeGuide.md#Common-Changes).
*
* - The previous `parse` implementation was renamed to `parseISO`.
*
* ```javascript
* // Before v2.0.0
* parse('2016-01-01')
*
* // v2.0.0 onward
* parseISO('2016-01-01')
* ```
*
* - `parseISO` now validates separate date and time values in ISO-8601 strings
* and returns `Invalid Date` if the date is invalid.
*
* ```javascript
* parseISO('2018-13-32')
* //=> Invalid Date
* ```
*
* - `parseISO` now doesn't fall back to `new Date` constructor
* if it fails to parse a string argument. Instead, it returns `Invalid Date`.
*
* @param {String} argument - the value to convert
* @param {Object} [options] - an object with options.
* @param {0|1|2} [options.additionalDigits=2] - the additional number of digits in the extended year format
* @returns {Date} the parsed date in the local time zone
* @throws {TypeError} 1 argument required
* @throws {RangeError} `options.additionalDigits` must be 0, 1 or 2
*
* @example
* // Convert string '2014-02-11T11:30:30' to date:
* var result = parseISO('2014-02-11T11:30:30')
* //=> Tue Feb 11 2014 11:30:30
