Android (Java) gregoriancalendar нечетное поведение ⇐ JAVA

[Anonymous]

У меня есть проблемы с java date type. Почему в мои кодовые дни и days1 оба Equall 88?

GregorianCalendar dateNow = new GregorianCalendar(2014,03,31);
GregorianCalendar dateFirstDay = new GregorianCalendar(2014,01,01);
long diffInMillies = dateNow. getTimeInMillis() - dateFirstDay. getTimeInMillis();
int days = (int) (diffInMillies / (1000*60*60*24));

GregorianCalendar dateNow1 = new GregorianCalendar(2014,04,01);
GregorianCalendar dateFirstDay1 = new GregorianCalendar(2014,01,01);
long diffInMillies1 = dateNow1. getTimeInMillis() - dateFirstDay1. getTimeInMillis();
int days1 = (int) (diffInMillies1 / (1000*60*60*24));
