211 Koha::Calendar - Object containing a branches calendar
215 This documentation refers to Koha::Calendar version 0.0.1
221 my $c = Koha::Calender->new( branchcode => 'MAIN' );
222 my $dt = DateTime->now();
225 $open = $c->is_holiday($dt);
226 # when will item be due if loan period = $dur (a DateTime::Duration object)
227 $duedate = $c->addDate($dt,$dur,'days');
232 Implements those features of C4::Calendar needed for Staffs Rolling Loans
236 =head2 new : Create a calendar object
238 my $calendar = Koha::Calendar->new( branchcode => 'MAIN' );
240 The option branchcode is required
245 my $dt = $calendar->addDate($date, $dur, $unit)
247 C<$date> is a DateTime object representing the starting date of the interval.
249 C<$offset> is a DateTime::Duration to add to it
251 C<$unit> is a string value 'days' or 'hours' toflag granularity of duration
253 Currently unit is only used to invoke Staffs return Monday at 10 am rule this
254 parameter will be removed when issuingrules properly cope with that
259 $yesno = $calendar->is_holiday($dt);
261 passed at DateTime object returns 1 if it is a closed day
262 0 if not according to the calendar
266 $duration = $calendar->days_between($start_dt, $end_dt);
268 Passed two dates returns a DateTime::Duration object measuring the length between them
273 Will croak if not passed a branchcode in new
275 =head1 BUGS AND LIMITATIONS
277 This only contains a limited subset of the functionality in C4::Calendar
278 Only enough to support Staffs Rolling loans
