Java s Calendar representation is not the best  they are working on it for Java 8  I would advise you to use Joda Time or another similar library   Here is a quick example using LocalDate from the Joda Time library   LocalDate localDate   new LocalDate year  month  day   Date date   localDate toDate      Here you can follow a quick start tutorial

java time  Using java time framework built into Java 8  int year   2015  int month   12  int day   22  LocalDate of year  month  day     2015-12-22 LocalDate parse  2015-12-22      2015-12-22   with custom formatter  DateTimeFormatter ofPattern formatter   DateTimeFormatter ofPattern  dd-MM-yyyy    LocalDate parse  22-12-2015   formatter     2015-12-22   If you need also information about time hour minute second  use some conversion from LocalDate to LocalDateTime  LocalDate parse  2015-12-22   atStartOfDay     2015-12-22T00 00

That s my favorite way prior to Java 8   Date date   new GregorianCalendar year  month - 1  day  getTime      I d say this is a cleaner approach than   calendar set year  month - 1  day  0  0

Months are zero-based in Calendar  So 12 is interpreted as december   1 month  Use   c set year  month - 1  day  0  0

Make your life easy when working with dates  timestamps and durations  Use HalDateTime from  http   sourceforge net projects haldatetime  source directory  For example you can just use it to parse your input like this   HalDateTime mydate   HalDateTime valueOf   25 12 1988     System out println  mydate         will print in ISO format  1988-12-25   You can also specify patterns for parsing and printing
