=head1 NAME

Date::GoldenNumber - Calculates the golden number used in John Conway's date calculations

=head1 SYNOPSIS

  use Date::GoldenNumber;
  $g = golden( 1992 );

=head1 DESCRIPTION

Most of John Conway's date calculation algorithms need the golden
number, which is Remainder(Y/19) + 1. Yes, this is very simple, but it
is inconvenient to have to rember this.
