NAME

Declination - Declination of the sun for each day of the year

SYNOPSIS

use Declination qw(declination);

my $date = DateTime->new(day=>21, month=>3, year=>2010);
my $declination	= declination($date, 'deg');

declination($date, [ $units])

Returns the declination of the sun on the given day of the year.

$date

A DateTime object. Only the day and month are relevant.

$units

The units to return, either 'rad' or 'deg'. This determines whether the result is returned as radians or degrees. If you are going to pass the result to trigonometric functions then radians are better. Default 'rad'.
