[Israel.pm] Date manipulations

A somewhat small addition:

Although Date::Calc is specified in scalars for the year, month and day, it
is easier to work using an @array  for the date where:

	$array[0] = $year;
	$array[1] = $month; 
	$array[2] = $day;

So:
	use strict;
	use warnings;
	use Date::Calc;
	
	...

	my @array = split "-'", $date_string;
 
	my $in_ten_days_it_will_be = Add_Delta_Days(@array, 10);

Happy dates manipulation!

Subject: [Israel.pm] Date manipulations

Hello,

I have date items of the form yyyy-mm-dd and I'd like to be able to
manipulate them in the following ways:

Given such a date I'd like to ask ordinal questions such as:
what was the date k days before (e.g., what is the date
yesterday) or what will be the date n days from that date (e.g., what's the
date 10 days later).

What's a practical way to go about this?

Thanks.
