SYNOPSIS

     use Calendar::Indonesia::Holiday qw(
         list_id_holidays
         enum_id_workdays
         count_id_workdays
     );

    This lists Indonesian holidays for the year 2011, without the joint
    leave days ("cuti bersama"), showing only the dates:

     my $res = list_id_holidays(year => 2011, is_joint_leave=>0);

    Sample result:

     [200, "OK", [
       '2011-01-01',
       '2011-02-03',
       '2011-02-16',
       '2011-03-05',
       '2011-04-22',
       '2011-05-17',
       '2011-06-02',
       '2011-06-29',
       '2011-08-17',
       '2011-08-31',
       '2011-09-01',
       '2011-11-07',
       '2011-11-27',
       '2011-12-25',
     ]];

    This lists religious Indonesian holidays, showing full details:

     my $res = list_id_holidays(year => 2011,
                                "tags.has" => ['religious'], detail=>1);

    Sample result:

     [200, "OK", [
       {date        => '2011-02-16',
        day         => 16,
        month       => 2,
        year        => 2011,
        ind_name    => 'Maulid Nabi Muhammad',
        eng_name    => 'Mawlid',
        eng_aliases => ['Mawlid An-Nabi'],
        ind_aliases => ['Maulud'],
        is_holiday  => 1,
        tags        => [qw/religious religion=islam calendar=lunar/],
       },
       ...
     ]];

    This checks whether 2011-02-16 is a holiday:

     my $res = list_id_holidays(date => '2011-02-16');
     print "2011-02-16 is a holiday\n" if @{$res->[2]};

    This enumerate working days for a certain period:

     my $res = enum_id_workdays(year=>2011, month=>7);

    Idem, but returns a number instead. year/month defaults to current
    year/month:

     my $res = count_id_workdays();

DESCRIPTION

FAQ

 What is "joint leave"?

    Workers are normally granted 12 days of paid leave per year. They are
    free to spend it on whichever days they want. The joint leave ("cuti
    bersama") is a government program of recent years (since 2002) to
    recommend that some of these leave days be spent together nationally on
    certain days, especially during Lebaran (Eid Ul-Fitr). It is not
    mandated, but many do follow it anyway, e.g. government civil workers,
    banks, etc. I am marking joint leave days with is_joint_leave=1 and
    is_holiday=0, while the holidays themselves with is_holiday=1, so you
    can differentiate/select both/either one.

 Holidays before 2002?

    Will be provided if there is demand and data source.

 Holidays after (current year)+1?

    Some religious holidays, especially Vesakha, are not determined yet.
    Joint leave days are also usually decreed by the government in May/June
    of the preceding year.

    governor election day for East Java province, etc).
