DateTime::Event::MultiCron is a perl module based on DateTime::Event::Cron, that allow to define a event with several cron schedules.

It was created because I have events that have diferent schedules definitions. It can be used, for example, to find the date/times for events that have diferent schedulings depending on the week day.

use DateTime::Event::MultiCron;

my $dts=DateTime::Event::MultiCron->from_multicron(

    '30 21 * * 2-5',

    #happens at 9h30pm from tuesday to friday



    '30 16,21 * * 6',

    #happens at 4h30pm and 9h30pm at satarday



    '30 15 * * 0'

    #happens at 3h30pm at sunday.

  );

You can download it from CPAN or from here.
