Want to make sure this date calcuation is correct

PHP

Hai folks,

my date : 2012/9/13

i need to calculate the total number of milliseconds before 60days of above date (my date - 60 days).

i have done the calcuation as follows and i just want to make sure its correct :slight_smile:


$mydate="2012/9/13"
$expdt=strtotime($mydate) - 5184000000; //5184000000 is the number of milliseconds in 60days.

Is the above correct?

Just to ask, are you then going to convert that number back to a date?

hai cups

i have another date will call ‘your date’ = ‘2012/10/13’, usually this date is after (greater than) ‘my date’.
so i want to calcuate the number of days between ‘my date’ and ‘your date’

the whole code i am writing will be like this



$mydate="2012/9/13";
$yourdate="2012/10/13";
$mydate=strtotime($mydate) - 5184000000; //5184000000 is the number of milliseconds in 60days.
$yourdate=strtotime($yourdate);
$days=round(($yourdate-$mydate) / 86400000); //not tested yet
