|

|
|

|

|
|
* 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://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
