to check if a date is today s date or not only check for dates not time included with that so make time 00 00 00 and use the code below      Calendar c   Calendar getInstance            set the calendar to start of today     c set Calendar HOUR OF DAY  0       c set Calendar MINUTE  0       c set Calendar SECOND  0       c set Calendar MILLISECOND  0        Date today   c getTime            or as a timestamp in milliseconds     long todayInMillis   c getTimeInMillis          int dayOfMonth   24      int month   4      int year  2013          reuse the calendar to set user specified date     c set Calendar YEAR  year       c set Calendar MONTH  month - 1       c set Calendar DAY OF MONTH  dayOfMonth       c set Calendar HOUR OF DAY  0       c set Calendar MINUTE  0       c set Calendar SECOND  0       c set Calendar MILLISECOND  0          and get that as a Date     Date dateSpecified   c getTime            test your condition     if  dateSpecified before today              Log v   date is previou         else if  dateSpecified equal today              Log v   date is today                        else if  dateSpecified after today              Log v   date is future date             Hope it will help

I assume you are using integers to represent your year  month  and day  If you want to remain consistent  use the Date methods    Calendar cal   new Calendar    int currentYear  currentMonth  currentDay   currentYear   cal get Calendar YEAR    currentMonth   cal get Calendar MONTH    currentDay   cal get Calendar DAY OF WEEK          if startYear  lt  currentYear                                                      message   message    Start Date is Before Today      n                                           else if startMonth  lt  currentMonth  amp  amp  startYear  lt   currentYear                                                                  message   message    Start Date is Before Today      n                                                 else if startDay  lt  currentDay  amp  amp  startMonth  lt   currentMonth  amp  amp  startYear  lt   currentYear                                                                              message   message    Start Date is Before Today      n
