[SOLVED] Calculating Dates

[gabrielp]

Hello there,

 

I need to do the following calculations... I have a starting date, and I need to know the exact date from that day + x number of months.

 

$start_date = '2008-01-11 06:38:44';

 

$qty_months = 13;

 

$final_date = ?????;

 

Thanks,

 

Gabriel.

Do it like this:

 

$start='2008-01-11 06:38:44'
$months_to_add=13;
$qty_years=floor($months_to_add/12);
$qty_months=$months_to_add%12;
$bits=explode("-",$start);
$year=$bits[0]
$month=$bits[1];
$newyear=$year+$qty_years;
$newmonth=$month+$qty_months;

$newdate=$newyear."-".$newmonth."-".$bits[2];

 

That's probably not the best way of doing it, but it should work. I'm assuming that your date format is YYYY-MM-DD, not YYYY-DD-MM.

This works GREAT

 

 

Thanks so much

A much simpler way:

<?php 
$start='2008-01-11 06:38:44';
$months_to_add=13;
$new_date = date('Y-m-d',strtotime($start . ' +' . $months_to_add . ' months'));
echo $new_date;
?>
