|
| 24 | * Return the date parsed from string using the given format string.
|
| 25 | *
|
| 26 | * > ⚠️ Please note that the `format` tokens differ from Moment.js and other libraries.
|

|
| 28 | *
|
| 29 | * The characters in the format string wrapped between two single quotes characters (') are escaped.
|
| 30 | * Two single quotes in a row, whether inside or outside a quoted sequence, represent a 'real' single quote.
|
| 31 | *
|
| 32 | * Format of the format string is based on Unicode Technical Standard #35:
|
| 33 | * https://www.unicode.org/reports/tr35/tr35-dates.html#Date_Field_Symbol_Table
|
| 34 | * with a few additions (see note 5 below the table).
|
| 35 | *
|
| 36 | * Not all tokens are compatible. Combinations that don't make sense or could lead to bugs are prohibited
|
| 37 | * and will throw `RangeError`. For example usage of 24-hour format token with AM/PM token will throw an exception:
|
| 38 | *
|
| 39 | * ```javascript
|
| 40 | * parse('23 AM', 'HH a', new Date())
|
| 41 | * //=> RangeError: The format string mustn't contain `HH` and `a` at the same time
|
| 42 | * ```
|
| 43 | *
|
| 44 | * See the compatibility table: https://docs.google.com/spreadsheets/d/e/2PACX-1vQOPU3xUhplll6dyoMmVUXHKl_8CRDs6_ueLmex3SoqwhuolkuN3O05l4rqx5h1dKX8eb46Ul-CCSrq/pubhtml?gid=0&single=true

|
| 192 | * Notes:
|
| 193 | * 1. "Formatting" units (e.g. formatting quarter) in the default en-US locale
|
| 194 | * are the same as "stand-alone" units, but are different in some languages.
|
| 195 | * "Formatting" units are declined according to the rules of the language
|
| 196 | * in the context of a date. "Stand-alone" units are always nominative singular.
|
| 197 | * In `format` function, they will produce different result:
|
| 198 | *
|
| 199 | * `format(new Date(2017, 10, 6), 'do LLLL', {locale: cs}) //=> '6. listopad'`
|
| 200 | *
|
| 201 | * `format(new Date(2017, 10, 6), 'do MMMM', {locale: cs}) //=> '6. listopadu'`
|
| 202 | *
|
| 203 | * `parse` will try to match both formatting and stand-alone units interchangably.
|
| 204 | *
|
| 205 | * 2. Any sequence of the identical letters is a pattern, unless it is escaped by
|
| 206 | * the single quote characters (see below).
|
| 207 | * If the sequence is longer than listed in table:
|
| 208 | * - for numerical units (`yyyyyyyy`) `parse` will try to match a number
|
| 209 | * as wide as the sequence
|
| 210 | * - for text units (`MMMMMMMM`) `parse` will try to match the widest variation of the unit.
|
| 211 | * These variations are marked with "2" in the last column of the table.
|
| 212 | *
|
| 213 | * 3. `QQQQQ` and `qqqqq` could be not strictly numerical in some locales.
|
| 214 | * These tokens represent the shortest form of the quarter.
|
| 215 | *
|
| 216 | * 4. The main difference between `y` and `u` patterns are B.C. years:
|
| 217 | *
|
| 218 | * | Year | `y` | `u` |
|
| 219 | * |------|-----|-----|
|
| 220 | * | AC 1 | 1 | 1 |
|
| 221 | * | BC 1 | 1 | 0 |
|
| 222 | * | BC 2 | 2 | -1 |
|
| 223 | *
|
| 224 | * Also `yy` will try to guess the century of two digit year by proximity with `referenceDate`:
|
| 225 | *
|
| 226 | * `parse('50', 'yy', new Date(2018, 0, 1)) //=> Sat Jan 01 2050 00:00:00`
|
| 227 | *
|
| 228 | * `parse('75', 'yy', new Date(2018, 0, 1)) //=> Wed Jan 01 1975 00:00:00`
|
| 229 | *
|
| 230 | * while `uu` will just assign the year as is:
|
| 231 | *
|
| 232 | * `parse('50', 'uu', new Date(2018, 0, 1)) //=> Sat Jan 01 0050 00:00:00`
|
| 233 | *
|
| 234 | * `parse('75', 'uu', new Date(2018, 0, 1)) //=> Tue Jan 01 0075 00:00:00`
|
| 235 | *
|
| 236 | * The same difference is true for local and ISO week-numbering years (`Y` and `R`),
|
| 237 | * except local week-numbering years are dependent on `options.weekStartsOn`
|
| 238 | * and `options.firstWeekContainsDate` (compare [setISOWeekYear](https://date-fns.org/docs/setISOWeekYear)
|
| 239 | * and [setWeekYear](https://date-fns.org/docs/setWeekYear)).
|
| 240 | *
|
| 241 | * 5. These patterns are not in the Unicode Technical Standard #35:
|
| 242 | * - `i`: ISO day of week
|
| 243 | * - `I`: ISO week of year
|
| 244 | * - `R`: ISO week-numbering year
|
| 245 | * - `o`: ordinal number modifier
|
| 246 | * - `P`: long localized date
|
| 247 | * - `p`: long localized time
|
| 248 | *
|
| 249 | * 6. `YY` and `YYYY` tokens represent week-numbering years but they are often confused with years.
|
| 250 | * You should enable `options.useAdditionalWeekYearTokens` to use them. See: https://github.com/date-fns/date-fns/blob/master/docs/unicodeTokens.md
|
| 251 | *
|
| 252 | * 7. `D` and `DD` tokens represent days of the year but they are ofthen confused with days of the month.
|
| 253 | * You should enable `options.useAdditionalDayOfYearTokens` to use them. See: https://github.com/date-fns/date-fns/blob/master/docs/unicodeTokens.md
|
| 254 | *
|
| 255 | * 8. `P+` tokens do not have a defined priority since they are merely aliases to other tokens based
|
| 256 | * on the given locale.
|
| 257 | *
|
| 258 | * using `en-US` locale: `P` => `MM/dd/yyyy`
|
| 259 | * using `en-US` locale: `p` => `hh:mm a`
|
| 260 | * using `pt-BR` locale: `P` => `dd/MM/yyyy`
|
| 261 | * using `pt-BR` locale: `p` => `HH:mm`
|
| 262 | *
|
| 263 | * Values will be assigned to the date in the descending order of its unit's priority.
|
| 264 | * Units of an equal priority overwrite each other in the order of appearance.
|
| 265 | *
|
| 266 | * If no values of higher priority are parsed (e.g. when parsing string 'January 1st' without a year),
|
| 267 | * the values will be taken from 3rd argument `referenceDate` which works as a context of parsing.
|
| 268 | *
|
| 269 | * `referenceDate` must be passed for correct work of the function.
|
| 270 | * If you're not sure which `referenceDate` to supply, create a new instance of Date:
|
| 271 | * `parse('02/11/2014', 'MM/dd/yyyy', new Date())`
|
| 272 | * In this case parsing will be done in the context of the current date.
|
| 273 | * If `referenceDate` is `Invalid Date` or a value not convertible to valid `Date`,
|
| 274 | * then `Invalid Date` will be returned.
|
| 275 | *
|
