It uses `Intl` to provide parsing support for all installed locales. ## Installation Option 1: NPM ```shell npm install any-date-parser ``` Option 2: CDN ```html ``` Option 3: CDN import ```html ``` ## Table of Contents 1.

[Contributing](#contributing) ## Breaking changes ### Upgrading from v1 => v2 - `fromString` and `fromAny` now return a `MaybeValidDate` instance that is a subclass of `Date`. Previously, they returned `Date | { invalid: string; }`. `MaybeValidDate` has an `invalid` property if invalid, and an `isValid()` function whether valid or not. If in v1 you simply checked for an `invalid` property, v2 will behave the same. - If an input string does not match any known format, it will attempt a fuzzy match, looking for date parts individually. - Custom patterns are no longer supported ## Motivation 1. The APIs I consume have a lot of different date formats 1. I want to create REST APIs that accept all major formats 1. I want to handle user-input dates 1. I want to support dates in other languages according to JavaScript's new `Intl` global object ## Usage There are three ways to use `any-date-parser`: 1.) Use the `parser` to get a Date: - `parser.fromAny(any, locale)` - Return a `Date` object given a `Date`, `Number` or string to parse. - `parser.fromString(string, locale)` - Parses a string and returns a `Date` object. Returns invalid if string is not a string Example: ```ts import parser from 'any-date-parser'; parser.fromString('2020-10-15'); // same as new Date(2020, 9, 15, 0, 0, 0, 0) ``` 2.) Use the `parser` to pull out known parts. The function `parser.attempt(string, locale)` returns an object with one or more integer values for the following keys: year, month, day, hour, minute, second, millisecond, offset. **Note:** month is returned as a normal 1-based integer, not the 0-based integer the `Date()` constructor uses. Examples: ```ts import parser from 'any-date-parser'; parser.attempt('15 Oct 2020 at 6pm'); /* returns: { year: 2020, month: 10, day: 15, hour: 18, } */ parser.attempt('Oct 15'); /* returns: { month: 10, day: 15, } */ parser.attempt('Hello world'); /* returns: { invalid: 'Unable to parse "Hello World"' } */ parser.attempt(''); /* returns: { invalid: 'Unable to parse "(empty string)"' } */ ``` 3.) Use the aliases on the `Date` constructor: - `Date.fromAny(any, locale)` - Return a `Date` object given a `Date`, `Number` or string to parse. - `Date.fromString(string, locale)` - Parses a string and returns a `Date` object. Returns invalid if string is not a string Example: ```ts import 'any-date-parser'; Date.fromString('2020-10-15'); // same as new Date(2020, 9, 15, 0, 0, 0, 0) ``` 4.) There are npm packages that integrate any-date-parser directly into popular date libraries: - Luxon: [luxon-parser](http://npmjs.com/package/luxon-parser) - DayJS: [dayjs-parser](http://npmjs.com/package/dayjs-parser) - Moment: [moment-parseplus](http://npmjs.com/package/moment-parseplus) \[deprecated\] ## Supported formats Summary: - 24 hour time - 12 hour time - timezone offsets - timezone abbreviations - year month day - year monthname day - month day year - monthname day year - day month year - day monthname year - +/-/ago periods - now/today/yesterday/tomorrow - Twitter - Fuzzy [Exhaustive list of date formats](#exhaustive-list-of-date-formats) ## Locale Support `any-date-parser` supports any locale that your runtime's [Intl.DateTimeFormat](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Intl/DateTimeFormat) supports. In browsers that usually means the operating system language. In Node, that means the compiled language or the icu modules included. The unit tests run on Bun, which ships with full ICU data, so every locale is available without any extra dependency. This means support for international formats such as: - `es-MX` - `viernes, 27 de septiembre de 2024, 10:39:50 a.m. GMT-6` - `bn-BD` - `শুক্রবার, ২৭ সেপ্টেম্বর, ২০২৪ এ ১০:৩৬:১০ AM GMT -৬` - `el-GR` - `Παρασκευή 27 Σεπτεμβρίου 2024 στις 10:38:16 π.μ. GMT-6` - `hi-IN` - `शुक्रवार, 27 सितंबर 2024 को 10:39:13 am GMT-6 बजे` - `th-TH` - `วันศุกร์ที่ 27 กันยายน พ.ศ. 2567 เวลา 10 นาฬิกา 40 นาที 28 วินาที GMT-6` - `ta-IN` - `வெள்ளி, 27 செப்டம்பர், 2024 அன்று 10:43:05 AM GMT-6` - `hu-HU` - `2024. szeptember 27., péntek 10:44:41 GMT-6` _Note_: For locales that use the Buddhist year (such as `th-TH`), any-date-parser automatically subtracts 543 years to normalize it to the Gregorian Calendar year. Check out the [list of all supported locales](https://github.com/kensnyder/any-date-parser/blob/master/test-fixtures/localeList.ts) ## Limitations - Dates with years before 1000 must have 4 digits, i.e. leading zeros. - any-date-parser cannot parse Dates before 0100 or after 9999 though JavaScript support is only limited where milliseconds is between `-8640000000000000 through 8640000000000000`, which allows a range of `-271821-04-20T00:00:00.000Z through +275760-09-13T00:00:00.000Z`. - Only English timezone names are supported - Does not support the Hijri calendar (`islamic-umalqura`) - Does not support right-to-left script locales such as `ar` (Arabic) and `he` (Hebrew) ## Unit tests Tests run on [Bun](https://bun.com). You can git checkout `any-date-parser` and run its tests. - To install dev dependencies, run `bun install` - To run tests, run `bun run test` (which is `bun test` with `TZ=UTC` set, so results do not vary with your machine's timezone) - To re-run tests on change, run `bun run test-watch` - To check coverage, run `bun run coverage` (prints a table and writes `coverage/lcov.info`) - _Note_ - Bun ships with full ICU data, so no extra i18n install step is needed ## Contributing Contributions are welcome.
