$oneDay = 86400; // number of seconds in a day
// 60 seconds * 60 minutes * 24 hours

$today = date( "U" ); // lookup the date() function

$oneWeekAgo = $today - ( $oneDay * 7 );
$1050Days = $today + ( $oneDay * 1050 );

echo "The date for one week ago is: ";
echo date( "F d, Y", $oneWeekAgo );

echo "1,050 days in the future is: ";
echo date( "F d, Y", $1050Days );


The unix timestamp is an awesome tool for date
arithmetic.  Time arithmetic uses the same logic
but on a smaller scale.

$oneMinute = 60; // seconds
$oneHour = 3600; // seconds; 60 seconds * 60 minutes

[PHP] Date/Time Arithmetic

[Erich Reimberg N.]

Hello,

   Is it possible to do some arithmetic with time/date values in PHP? 
for example, to calculate:

   today + 1050 days.
   today - 7 days.
   etc.

I mean, does PHP have functions to perform these operations? 

Thanks,
Erich Reimberg.

PS. I'm new to PHP, and I didn't find anything like this in the FAQ
