val cal = Calendar.getInstance() val date =cal.get(Calendar.DATE ) val Year =cal.get(Calendar.YEAR ) val Month1 =cal.get(Calendar.MONTH ) val Month = Month1+1 Month is added with one because month starts with zero index.

When you are talking about year, month, day-of-month, hour-of-day etc... your timezone becomes very important. So whenever you are talking about all these, you have to mention the timezone.
If you are using java 8, you can use the java.time api
import java.time.{ZonedDateTime, ZonedOffset} // val yourTimeZoneOffset = ZoneOffset.ofHoursMinutesSeconds(hour, minute, second) // for example IST or Indian Standard Time has an offset of "+05:30:00" hrs val istOffset = ZoneOffset.ofHoursMinutesSeconds(5, 30, 0) // istOffset: java.time.ZoneOffset = +05:30 // time representation in IST val zonedDateTimeIst = ZonedDateTime.now(istOffset) // zonedDateTimeIst: java.time.ZonedDateTime = 2016-09-29T20:14:48.048+05:30 val year = zonedDateTimeIst.getYear // year: Int = 2016 val month = zonedDateTimeIst.getMonth // month: java.time.Month = SEPTEMBER val dayOfMonth = zonedDateTimeIst.getDayOfMonth // dayOfMonth: Int = 29 val df1 = DateTimeFormatter.ofPattern("yyyy - MM - dd") val df2 = DateTimeFormatter.ofPattern("yyyy/MM/dd") // df1: java.time.format.DateTimeFormatter = Value(YearOfEra,4,19,EXCEEDS_PAD)' ''-'' 'Value(MonthOfYear,2)' ''-'' 'Value(DayOfMonth,2) // df2: java.time.format.DateTimeFormatter = Value(YearOfEra,4,19,EXCEEDS_PAD)'/'Value(MonthOfYear,2)'/'Value(DayOfMonth,2) val dateString1 = zonedDateTimeIst.format(df1) // dateString1: String = 2016 - 09 - 29 val dateString2 = zonedDateTimeIst.format(df2) // dateString2: String = 2016/09/29

You could use joda-time:
import org.joda.time.DateTime val date: String = DateTimeFormat.forPattern("yyyy-MM-dd").print(DateTime.now()) val month: Int = DateTime.now().getMonthOfYear val year: Int = DateTime.now().getYear In case you use java8 you could also use the native DateTime API, which is designed after the joda-time api.

You need to use different SimpleDateFormat objects for that purpose as described here
In your case, you'll need :
import java.text.SimpleDateFormat val minuteFormat = new SimpleDateFormat("MM") val yearFormat = new SimpleDateFormat("YYYY") val dayFormat = new SimpleDateFormat("dd") And then, to get for example, the year for a given date, simply use :
val currentYear = hourFormat.format(yourDate)
