⌚Kotlin intuitive Date extensions.

tempo

Kotlin intuitive java.util.Date extensions.

Usage

val now: Date = Tempo.now               //=> now
now + 1.week                            //=> next week 
now - 2.days                            //=> day before yesterday
now + (3.weeks - 4.days + 5.hours)      //=> somewhere in 2 and a half weeks

Tempo.tomorrow                          //=> tomorrow
Tempo.yesterday                         //=> yesterday
1.day.ago                               //=> yesterday
3.weeks.ago                             //=> 3 weeks ago
5.years.forward                         //=> five years in the future 

Initialize by specifying date components

Tempo.with(year = 1990, month = 1, day = 21)    //=> 1990/01/21
Tempo.with(year = 2019, month = 6, day = 26, hour = 18, minute = 58, second = 31, millisecond = 777)

Initialize by changing date components

Tempo.now.with(month = 12, day = 25)    //=> this year's christmas
Date().with(month = 12, day = 25)       //=> this year's christmas

// shortcuts
Tempo.now.beginningOfYear     //=> new year's day
Tempo.now.endOfYear           //=> new year's eve

Check day of the week / properties

Tempo.now.isMonday
Tempo.now.isTuesday
Tempo.now.isWednesday
Tempo.now.isThursday
Tempo.now.isFriday
Tempo.now.isSaturday
Tempo.now.isSunday
Tempo.now.isWeekend
Tempo.now.isWeekday

Tempo.now.isToday                       // true
Tempo.tomorrow.isToday                  // false
Tempo.tomorrow.isTomorrow               // true
Tempo.yesterday.isYesterday             // true

Format and parse

5.minutes.forward.toString("yyyy-MM-dd HH:mm:ss")
//=> "2019-06-11 12:05:00"

"1988-03-02".toDate("yyyy-MM-dd")
//=> Tempo.with(year = 1988, month = 3, day = 2)

Compare dates

1.day.ago > 2.days.ago                  // true
1.day.ago in 2.days.ago..Tempo.now      // true
