Printing every 3 weeks blocks

[Canman2005]

Hi all

 

I have a database field called `date` this stores a datestamp in the following format

 

YYYY-MM-DD

 

I have a PHP page which I run everyday, I want to print the word

 

"process"

 

If it has been 3 weeks since the value of the field `date`.

 

So for example, if my `date` value was 2009-02-01, and I loaded the page and it was 3 weeks since that date, it would print "process", if it was 6 weeks since that date it would print "process" and if it was 9 weeks since that date, it would print "process".

 

So as you can see, im trying to figure out 3 week blocks since the `date` value

 

Does that make sense? Can anyone help?

 

Thanks in advance
