VERSION

version 0.07

SYNOPSIS

# procedural approach

my ($year, $month, $day) = (localtime)[ 5, 4, 3 ];
$year  += 1900;
$month += 1;

print 'Woot!' if is_holiday($year, $month, $day, {province => 'BC'});

my $calendar = $dhc->holidays_dt(DateTime->today->year);
print join keys %$calendar, "\n";       # lists holiday names for QC

Object Methods

get()

Retrieve fields of a Date::Holidays::CA object.

$prov = $dhc->('province');

set()

Alter fields of a Date::Holidays::CA object. Specify parameters just as with new().

$dhc->set({province => 'QC', language => 'FR/EN'});

Combination Methods

These methods are callable in either object-oriented or procedural style.

is_holiday()

For a given year, month (1-12) and day (1-31), return 1 if the given day is a holiday; 0 if not. When using procedural calling style, an additional hashref of options can be specified.

$holiday_p = is_holiday($year, $month, $day);

$holiday_p = is_holiday($year, $month, $day, {
    province => 'BC', language => 'EN'
});

$holiday_p = $dhc->is_holiday($year, $month, $day);

is_ca_holiday()

Similar to is_holiday. Return the name of the holiday occurring on the specified date if there is one; undef if there isn't.

print $dhc->is_ca_holiday(2001, 1, 1);          # "New Year's Day"

is_holiday_dt()

As is_holiday, but accepts a DateTime object in place of a numeric year, month, and day.

$holiday_p = is_holiday($dt, {province => 'SK', language => 'EN'});

$holiday_p = $dhc->is_holiday($dt);

holidays()

For the given year, return a hashref containing all the holidays for that year. The keys are the date of the holiday in mmdd format (eg '1225' for December 25); the values are the holiday names.

my $calendar = holidays($year, {province => 'MB', language => 'EN'});
#returns a hash reference
print $calendar->{'0701'};               # "Canada Day"

my $calendar = $dhc->holidays($year);
#returns a hash reference
print $calendar->{'1111'};               # "Remembrance Day"

ca_holidays()

Same as holidays().

holidays_dt()

Similar to holidays(), after a fashion: returns a hashref with the holiday names as the keys and DateTime objects as the values.

my $calendar = $dhc->holidays_dt($year);

SPECIFICATIONS

New Year's Day

KNOWN BUGS

Historical holidays are not supported; the current set of holidays will be projected into the past or future. For instance, Louis Riel Day was added as a Manitoba holiday in 2008, but if you use this module to generate a holiday list for 2007, Louis Riel Day will be present. Also, PEI's Islander Day was first observed on the second Monday of 2009, but will subsequently be observed on the third Monday of the month; this module will always show it as occurring on the third Monday. This will be addressed if there is demand to do so.

Several lesser holidays are not yet implemented:

Calgary Stampede

I am told that the morning of the Stampede Parade is commonly given as a half-day holiday by employers within the city of Calgary, but I haven't been able to verify this, nor does there seem to be a way to mathematically calculate when parade day will be scheduled.

St Johns Regatta Day

Regatta Day is a municipal holiday in St Johns, NL, and it is scheduled for the first Wednesday in August. However, if the weather on Quidi Vidi Lake does not look promising on Regatta morning, the event (and the attendant holiday) are postponed until the next suitable day.

How to programatically determine the day of this holiday has not yet been satisfactorily ascertained. Acme::Test::Weather has been considered.

Gold Cup and Saucer Day (PEI)

Some few employees apparently get the day of the Gold Cup and Saucer harness race as a holiday, but I haven't been able to independently verify this.

Construction Holiday (Quebec)

In Quebec, the vast majority of the construction industry gets the last full two weeks of July off, and it's also a popular time for other folks to book vacation. Since this technically only applies to a single industry, I haven't added it to this module, but I will if there is sufficient demand.

HELP WANTED

As you can see from the KNOWN BUGS section above, our holiday structure can be fairly baroque. Different provinces and cities get different holidays; sometimes these are paid statutory holidays that are included in Employment Standards legislation; other times they are unofficial holidays that are given by convention and codified only in collective agreements and municipal by-laws. Thus, it's hard to know what's commonly considered "a holiday" in the various regions of the country without actually having lived and worked there.

I only have direct experience with British Columbia and Ontario; my impression of what folks in other provinces consider to be a holiday is based on research on the WWW. I've tried to define a holiday as any day when "the majority of the workforce either get the day off (paid or unpaid) or receive pay in lieu." If the holidays list in this module doesn't accurately reflect the application of that definition to your region of Canada, I'd like to hear about it.

Assistance with French translations of the holiday names and this documentation is most welcome. My French isn't all that great, but I'm happy to learn. =)

Finally, I'd appreciate an email from any users of this module. I'm curious to know who has picked it up, and any feedback you might have will shape its future development.

CAVEATS

For reasons outlined in the two sections above, please be forewarned that what days are considered holidays may change with versions of the module.

Note that the holiday is intended to reflect the actual observed holiday not the date of the actual day. Christmas Day, for example, is December 25th but the actual day of the holiday may be two days later, the Monday, if Christmas Day is on a Saturday.
