Astro::Sunrise - Calculate sunrise/sunset for a date and location
$ cat ./examples/example.raku #!/usr/bin/env raku use lib <./lib ../lib>; use Astro::Sunrise; use Astro::Location; # use a location in './t/tests.dat': # Amsterdam, Netherlands 52 22 N 4 53 E sunrise: 03:16 sunset: 20:09 my $loc = Location.new: :city<Amsterdam>, :state(''), :country<NL>, :lat(52+22/60), :lon(4+53/60), :timezone<Europe/Amsterdam>, # from Wikipedia :tz(+1), # from Wikipedia ; # use the date from the test file '/t/01basic.t' my $year = 2003; my $month = 6; my $day = 21; # Note positional args, be careful! A list of two DateTime objects # are returned. The tz value should NOT be applied as an input when # testing for sunrise/sunset times using the original test data. my ($rise, $set) = sunrise $year, $month, $day, $loc.lon, $loc.lat; # Output times as my $sunrise = sprintf '%02d%02dZ', $rise.hour, $rise.minute; my $sunset = sprintf '%02d%02dZ', $set.hour, $set.minute; say $sunrise; # expected: 0316Z say $sunset; # expected: 2009Z
