The first two lines of the code I posted originally should be:

if($days < 0) {
$fakeStartDateString = $s->format(‘Y’).”-”.($e->format(‘m’)-1).”-”.$s->format(‘d’);

Sorry for flooding your post.

if ($days format(‘Y’).”-”.($e->format(‘m’)-1).”-”.$s->format(‘d’);

if($days format(‘Y’).”-”.($e->format(‘m’)-1).”-”.$s->format(‘d’);

Thanks for posting your function. After using it with several different birth dates I found that the days were not being calculated correctly. The problem was the correction of negatives days, which substracts the start date day from the total number of days in the start date month, when they should be subsctracted from the last completed month (end date month – 1).

This is what I did:


// We cannot have negative days
// Calculate how many days are in the startdate month // Not the startdate month, but the last completed month (end date month - 1)
// subtract the startdate day and add 1 // Not necessary to add 1
// Then add back in the day of the enddate
// Subtract 1 month
if ($days format('Y')."-".($e->format('m')-1)."-".$s->format('d');
$fakeStartDate = new DateTime($fakeStartDateString);
$days = $fakeStartDate->format('t')-$s->format('d');
//$days = $s->format('t')-$s->format('d');//+1;
$days += $e->format('d');
$months--;
}


It now works perfectly fine.

I hope someone finds this useful.

It is exactly what I needed to calculate the exact difference between 2 dates.
You saved me a lot of time!
