207 Koha::Calendar - Object containing a branches calendar
211 This documentation refers to Koha::Calendar version 0.0.1
217 my $c = Koha::Calender->new( branchcode => 'MAIN' );
218 my $dt = DateTime->now();
221 $open = $c->is_holiday($dt);
222 # when will item be due if loan period = $dur (a DateTime::Duration object)
223 $duedate = $c->addDate($dt,$dur,'days');
228 Implements those features of C4::Calendar needed for Staffs Rolling Loans
232 =head2 new : Create a calendar object
234 my $calendar = Koha::Calendar->new( branchcode => 'MAIN' );
236 The option branchcode is required
241 my $dt = $calendar->addDate($date, $dur, $unit)
243 C<$date> is a DateTime object representing the starting date of the interval.
245 C<$offset> is a DateTime::Duration to add to it
247 C<$unit> is a string value 'days' or 'hours' toflag granularity of duration
249 Currently unit is only used to invoke Staffs return Monday at 10 am rule this
250 parameter will be removed when issuingrules properly cope with that
255 $yesno = $calendar->is_holiday($dt);
257 passed at DateTime object returns 1 if it is a closed day
258 0 if not according to the calendar
262 $duration = $calendar->days_between($start_dt, $end_dt);
264 Passed two dates returns a DateTime::Duration object measuring the length between them
269 Will croak if not passed a branchcode in new
271 =head1 BUGS AND LIMITATIONS
273 This only contains a limited subset of the functionality in C4::Calendar
274 Only enough to support Staffs Rolling loans
