// What date is next thursday? Date.today().next().thursday(); // Add 3 days to Today Date.today().add(3).days(); // Is today Friday? Date.today().is().friday();
It also does quite a bit of natural English parsing, like
Date.parse(‘next thursday’), although most date libraries support that too. I think the chainable interface stands out here as something special. Let's contrast that with some perl code to calculate yesterday, shall we??
my @lt = localtime(time - 86400); return ($lt+1900) .'-' . ($lt+1) . '-' . ($lt);
(Disclaimer: I didn't actually write that, but it's in a legacy app I sometimes maintain. I'm sure there is a cleaner way in perl to write that code, I just wouldn't know it, nor do I care to!)
