Jiffy().format("MMMM dd yyyy, h:mm:ss a"); // October 19 2019, 7:00:53 PM
Jiffy().format("EEEE"); // Saturday
Jiffy("2019-10-2").format("yyyy 'escaped' yyyy"); // 2019 escaped 2019
Jiffy().format(); // 2019-10-19T19:00:53.090646

Jiffy([2019, 10, 19]).yMMMMd; // October 19, 2019
Jiffy({
  "year": 2019,
  "month": 10,
  "day": 19,
  "hour": 19
}).yMMMMEEEEdjm; // Saturday, October 19, 2019 7:00 PM

//  You can also use default formats
Jiffy("19, Oct 2019", "dd, MMM yyyy").yMMMMd; // October 19, 2019
Jiffy().yMMMMEEEEdjm; // Saturday, October 19, 2019 7:00 PM

Relative Time

Jiffy("2011-10-31", "yyyy-MM-dd").fromNow(); // 8 years ago
Jiffy("2012-06-20").fromNow(); // 7 years ago

var jiffy1 = Jiffy()
    ..startOf("day");
jiffy1.fromNow(); // 19 hours ago

var jiffy2 = Jiffy()
    ..endOf("day");
jiffy2.fromNow(); // in 5 hours

var jiffy3 = Jiffy()
    ..startOf("hour");
jiffy3.fromNow(); // 9 minutes ago

Manipulation

var jiffy1 = Jiffy()
    ..add(duration: Duration(days: 1));
jiffy1.yMMMMd; // October 20, 2019

var jiffy2 = Jiffy()
    ..subtract(days: 1);
jiffy2.yMMMMd; // October 18, 2019

//  You can chain methods by using Dart method cascading
var jiffy3 = Jiffy()
    ..add(days: 1)
    ..add(hours: 3)
    ..subtract(minutes: 30);
jiffy3.yMMMMEEEEdjm; // Sunday, October 20, 2019 9:50 PM

var jiffy4 = Jiffy()
    ..add(duration: Duration(days: 1))
    ..add(duration: Duration(hours: 3))
    ..subtract(duration: Duration(minutes: 30));
jiffy4.format("dd/MM/yyy"); // 20/10/2019


// Months and year are added in respect to how many days there are in a months and if is a year is a leap year
Jiffy("2010-1-31", "yyyy-MM-dd"); // This is January 31
Jiffy("2010-1-31", "yyyy-MM-dd").add(months: 1); // This is February 28
