import { parseSchedule } from 'date-parrot'

parseSchedule('eat donuts on every 3rd friday')

//   schedule: {
//     repeatFrequency: 'P1W',
//     startDate: '[NEXT_FRIDAY_AS_ISO_STRING]',

Localization

By default DateParrot only parses english but you can add support for other languages by adding a locales property to the config of the parser functions.

It takes an array of locale identifiers (e.g. ['en', 'de']).

import { parseDate } from 'date-parrot'

parseDate('lass uns morgen ausgehen', { locales: ['de'] })

// =>
// {
//   date: [TOMORROW_AS_ISO_STRING],
//   match: {
//     index: 9,
//     length: 6,
//     text: 'morgen',
//   },
// }
