Programming Tips - Java: get the 12-hour time when I am using Calendar? (Eg 1pm for 13:00)

Date: 2011oct28 Language: Java Keywords: GregorianCalendar Q. Java: get the 12-hour time when I am using Calendar? (Eg 1pm for 13:00) A. Calendar has HOUR (which seems to be a 12-hour time) and HOUR_OF_DAY (which is the 24-hour time). But HOUR gives an unexpected result from noon to 1pm and midnight to 1am. It is 0 instead of 12.
int hour_wrong = mycal.get(Calendar.HOUR); // WRONG
So I prefer to use HOUR_OF_DAY and convert it myself:
int get12Hour(Calendar cal) { int hour = cal.get(Calendar.HOUR_OF_DAY); if (hour == 0) hour = 12; // at 30 minutes into the day we want 12:30 not 00:30 if (hour > 12) hour -= 12; return hour; }
