Difference in timestamps off due to leap year?

[tresmom5]

I admit to being not very good at php. I am trying to just find out the difference between today's date and a future date in weeks and days in php.

$actual_timestamp = time();
$remaining_seconds = $future_timestamp - $actual_timestamp;
$remaining_days = floor($remaining_seconds / (60*60*24));

I used this and then divided the $remaining days/7 to get the weeks.

I am off a day due to leap year. How do I fix this?

Have you considered converting the dates to julian dates before performing the math? PHP has Calendar Functions [php.net] that you may find useful.

$actual_timestamp = time(); 
$remaining_days  = unixtojd($future_timestamp) - unixtojd($actual_timestamp); 
$remaining_weeks = floor($remaining_days/7);
