I want to get Date from DB and get from date year, month, day, hour and minutes The way i'm doing it is: Date dateStart = calendarEvents.getDateStart(); java.util Just use: SimpleDateFormat // Create an instance of SimpleDateFormat used for formatting // the string representation of date (month/day/year) DateFormat df = new SimpleDateFormat("MM/dd/yyyy HH:mm:ss"); // Get the date today using Calendar object. Here is a Kotlin extension of the Date class returning the age corresponding to a Date object. val Date.age: Int get () { val calendar = Calendar.getInstance () calendar.time = Date (time - Date ().time) return 1970 - (calendar.get (Calendar.YEAR) + 1) } It is compatible for all Android versions. If you wonder what '1970' is, that's the Unix Epoch. A simple adjuster might simply set the one of the fields, such as the year field. A more complex adjuster might set the date to the last day of the month. A selection of common adjustments is provided in TemporalAdjusters. These include finding the "last day of the month" and "next Wednesday". const d = new Date (); d.setDate(15); Try it Yourself ». The setDate () method can also be used to add days to a date: Example. const d = new Date (); d.setDate(d.getDate() + 50); Try it Yourself ». If adding days shifts the month or year, the changes are handled automatically by the Date object. What idiot designs a Date class where year is 1900-based, month is 0-based, but day is 1-based? No consistency whatsoever. Ludicrous!--- Even Calendar, where year is fixed to be 0-based, still has 0-based month and 1-based day. No wonder they are both very error-prone to use. .
