+ * @name format
+ * @category Common Helpers
+ * @summary Format the date.
+ *
+ * @description
+ * Return the formatted date string in the given format. The result may vary by locale.
+ *
+ * > ⚠️ Please note that the `format` tokens differ from Moment.js and other libraries.
+ * > See: https://github.com/date-fns/date-fns/blob/master/docs/unicodeTokens.md
+ *
+ * The characters 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.
+ * (see the last example)
+ *
+ * Format of the 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 7 below the table).
+ *

+ * 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. See: https://github.com/date-fns/date-fns/blob/master/docs/unicodeTokens.md
