Hi,

I need to compare two date values. The first value is today's date minus 6 months. the second date is taken from some data in the following format 010410 (this example would be 1st Aprril 2010).

What is the best method to do this?

The second date is an employees date of which they joined the company. Certain benefits are available to people who have been with the company for 6 months or longer.

010410 is not a date/time, but a string (which can be interpreted as a date/time)

to do this in php: date_parse_from_format:
http://www.php.net/manual/en/function.date-parse-from-format.php

once you have true (php) date/time values, you can easily use >= and <= operators on the values...

If you use MySql, you can do with query as following;

$sql = "select date_format(joindate,'%d%m%y') as joindate
from  tablename where joindate between date_add(curdate(), interval -6 Month) and curdate()";

try this.

$vdate="010410";
$time2 = strtotime(substr($vdate,0,2).".".substr($vdate,4,2).".".substr($vdate,6,2));
$time1 = strtotime("- 6 months");

if ($time2 < $time1) {
      ....
}

$e_date = "010410";
$exp_date = substr($e_date,0,2)."/".substr($e_date,2,2)."/".substr($e_date, -2);

$expiration_date = strtotime($exp_date);
$today_6 = strtotime("-6 months");

if ($expiration_date < $today_6) {
    echo 'ok';
}

This works perfectly for PHP version 5.2. I switched the the first two strings (day month) over to cover the UK date format.

Thanks very much,
Dan
