NAME
Date::Holidays::TW - Determine whether it is Taiwan Holidays or not.
SYNOPSIS
This module can be used by itself:
use Date::Holidays::TW qw(is_tw_holiday);
if ( is_tw_holiday(2020, 6, 25) ) {
...
}
Or via Date::Holidays
my $dh = Date::Holidays->new( countrycode => 'TW' );
if ($dh->is_holiday( 2020, 6, 25 )) {
...
}
DESCRIPTION
This module provides functions to look into Taiwan holiday calendars
for known holidays. It could be used by itself, or under via
Date::Holidays module.
Caveat: Due to the rule of weekend-compensation and the fact that the
majority of holidays are defined by Chinese calendar (Lunar), it
requires some non-trivial amount of computation to correctly determine
whether the given date is an holiday or not -- which is not implemented
at this version.
The current implementation includes all known holidays of year 2019 and
2020 as a lookup table and should therefore correctly determine
holidays in those 2 years. It should also determine most of the future
updates correct by some basic compuation, except for the ones generated
by the weekend-compensation rule.
Conventionally the holiday calendar for the next year is announcend at
the end of June and we could start to mix the new information into the
lookup table in this module.
Generally speaking, queries for far future should be avoided.
