Dint

A port of Dint, a minimalistic library to handle dates as easy as you handle simple integers.

Dint is an integer which contains date in a human-readable integer format: YYYYMMDD.

Example: 20140912 = September 12, 2014

Benefits are obvious:

• Dint does not have timezone information, it does not have time information, all operations are extremely simple. Your user will never get a wrong date because his timezone changed.
• Storage in a database is trivial.
• Easy to debug (in a human readable format).
• The entire library size is 2Kb. There is just a couple of math functions!

Usage

dint := Dint{}.create(2014, 9, 12) // creates a dint
fmt.Println(strconv.Itoa(dint))    // "20140912" - human-readable

Dint{}.addDays(dint, 199) // adds 199 days to a dint

if dint1 < dint2 { // Simple comparison
}

daysBetween := Dint{}.diff(20150912, 20140912) // = 365
fmt.Println(daysBetween)

asDate := Dint{}.toDate(dint) // Simple conversion
fmt.Println(asDate)

Dint{}.year(20140912)  // 2014
Dint{}.month(20140912) // 9
Dint{}.day(20140912)   // 12

Dint{}.compose(2014, 13, 12)    // 20150112!
Dint{}.compose(2013, 9, 12+365) // 20140912!

Dint{}.addMonths(20140930, 1)       // 20141030
Dint{}.addMonthsExtend(20140930, 1) // 20141031 keeps the last day of month!
