Format Dates

Jiffy.parse('2021/01/19').format(pattern: 'MMMM do yyyy, h:mm:ss a'); // January 19th 2021, 12:00:00 AM
Jiffy.now().format(pattern: 'EEEE'); // Tuesday
Jiffy.now().format(pattern: 'MMM do yy'); // Mar 2nd 21
Jiffy.now().format(pattern: 'yyyy [escaped] yyyy'); // 2021 escaped 2021
Jiffy.now().format(); // 2021-03-02T15:18:29.922343

Jiffy.parseFromList([2020, 10, 19]).yMMMMd; // January 19, 2021

Jiffy.parseFromMap({
  Unit.year: 2020,
  Unit.month: 10,
  Unit.day: 19,
  Unit.hour: 19
}).dMMMMEEEEyjm; // Monday, October 19, 2020 7:14 PM

//  You can also use pre-set formats
Jiffy.parse('19, Jan 2021', pattern: 'dd, MMM yyyy').yMMMMd; // January 19, 2021
Jiffy.now().yMMMMEEEEdjm; // Tuesday, March 2, 2021 3:20 PM

Relative Time

// From X
Jiffy.parse('1997/09/23').from(Jiffy.parse('2002/10/26')); // 5 years ago
// From Now
Jiffy.parse('1997/09/23').fromNow(); // 25 years ago

// To X
Jiffy.parse('1997/09/23').to(Jiffy.parse('2002/10/26')); // in 5 years
// To Now
Jiffy.parse('1997/09/23').toNow(); // in 25 years

Manipulation

var jiffy = Jiffy.now().add(days: 1);
jiffy.yMMMMd; // March 3, 2021

Jiffy.now().subtract(days: 1).yMMMMd; // March 2, 2021

Jiffy.now()
  .add(hours: 3, days: 1)
  .subtract(minutes: 30, months: 1)
  .yMMMMEEEEdjm; // Wednesday, February 3, 2021 6:07 PM

Jiffy.parse('1997/09/23')
    .startOf(Unit.year)
    .yMMMMEEEEd; // Wednesday, January 1, 1997

Jiffy.parse('1997/09/23')
    .endOf(Unit.month)
    .yMMMMEEEEd; // Tuesday, September 30, 1997

Querying

Jiffy.parse('1997/9/23').isBefore(Jiffy.parse('1997/9/24')); // true

Jiffy.parse('1997/9/23').isAfter(Jiffy.parse('1997/9/20')); // true

Jiffy.parse('1997/9/23').isSame(Jiffy.parse('1997/9/23')); // true

Jiffy.parse('1997/9/23')
  .isBetween(Jiffy.parse('1997/9/20'), Jiffy.parse('1997/9/24')); // true

Locale Support

// Get current locale code, by default it is en_us
Jiffy.now().localeCode; // en_US

// Setting your preferred locale
await Jiffy.setLocale('fr_ca');
Jiffy.now().yMMMMEEEEdjm; // dimanche 26 février 2023 12 h 03

await Jiffy.setLocale('ja');
Jiffy.now().yMMMMEEEEdjm; // 2023年2月26日日曜日 12:02

await Jiffy.setLocale('zh_cn');
Jiffy.now().yMMMMEEEEdjm; // 2023年2月26日星期日 下午12:03
