For a list of more appropriate places to ask for help using PHP, please visit http://www.php.net/support.php as this bug system is not the appropriate forum for asking support questions. Due to the volume of reports we can not explain in detail here why your report is not a bug. The support channels will be able to provide an explanation for you. Thank you for your interest in PHP. Can't you just use days property of the interval object? In any case, this does not look like a fixable bug report, so closing it. If you have a proposal for a specific fix, please reopen.

When I "diff" two dates, and the function returns i.e. "1 month" and "1 day", what does it means with "1 month"? How many days has one month? Is it a variable quantity depending on the specific month we consider, or should I assume a "standard"/"normalized"/"conventional" quantity of 30 days? Is it managed? A month "concept" in a difference cannot have identity (how can I say we're speaking about february when I diff two dates?) So, because I have to calculate it with precision, how do I have to consider "1 month"? The result could be: 28+1=29 days 29+1=30 days 30+1=31 days 31+1=32 days 3 days of error are not acceptable, I suppose somebody gave to this a sense. You could suggest to me to use "getTimestamp" but passing trough epoch time causes errors for dates before 1970 and after 2038... The same for "year" concept: 365 or 366 days??? This info I'm requesting should be on top of the documentation page!!!!! Please, fix it!
