NAME
    DateTime::Schedule - Determine scheduled days in range based on
    exclusions

SYNOPSIS
      use DateTime::Schedule;

      my $dts = DateTime::Schedule->new(exclude => [
        DateTime->new(year => 2024, month => 01, day => 01),
        DateTime->new(year => 2024, month => 07, day => 04),
        DateTime->new(year => 2024, month => 12, day => 25)
      ]);

      my $start = DateTime->new(year => 2024, month => 1, day => 1);
      my $end = DateTime->new(year => 2024, month => 12, day => 31);
      print $dts->days_in_range($start, $end)->count; # 363

DESCRIPTION
    This is a simple class that allows you to find out which days are
    "scheduled" between a start date and an end date. For instance, given
    the start date of a school year, and the current date, and with all
    school holidays entered as "exclude"d, this can tell you how many school
    days have elapsed in the year.

CONSTRUCTORS
  new
    Default constructor. Returns a new DateTime::Schedule instance.

    Parameters:

   portion
    *Optional*. Default 1.

    A number between 0 and 1 indicating how much of a day must elapse to be
    included/excluded at the boundaries of the range.

   exclude
    *Optional*. Default "[]"

    An arrayref of DateTimes. These days are exclusions to the normal
    schedule (e.g., holidays). Any time-portion of the DateTimes is ignored.

METHODS
  days_in_range($start, $end)
    Given start/end DateTimes, returns a DateTime::Set of all the days which
    are scheduled (i.e., not excluded)
