The problem is that the subtraction of the two dates leaves me double identical value.

From : Thu Nov 29 00:00:00 CET 2012

Value 121: To: Sat Mar 30 00:00:00 CET 2013

Value 122: To: Sun Mar 31 00:00:00 CET 2013

Value 122: To: Mon Apr 01 00:00:00 CEST 2013

Value 123: To: Tue Apr 02 00:00:00 CEST 2013

Long today = (To.getTime() - From.getTime()) / (1000 * 60 * 60 * 24);

Is it possible to somehow avoid that logically? (sorry for English)

I didn't understand what you meant by **double identical value**. Could you be more clear? – aa8y Feb 28 '13 at 09:23
What is the result you expected? – sp00m Feb 28 '13 at 09:23
Subtracting two different dates I have the same result :P – Maury Feb 28 '13 at 09:24
They are dates in different time zones you can't directly substract them. Apples with apples. Use Calendar to operate, then convert them out of the calendar – Miquel Feb 28 '13 at 09:26
time zone is the same, and I use Calendar [..].add(Calendar.DATE, 1) – Maury Feb 28 '13 at 09:27
CET and CEST are not same thing – Miquel Feb 28 '13 at 09:28
yes i know, whether it is the possibility of subtracting the time>? – Maury Feb 28 '13 at 09:35
