Horde_Date_Recurrence
in package
The Horde_Date_Recurrence class implements algorithms for calculating recurrences of events, including several recurrence types, intervals, exceptions, and conversion from and to vCalendar and iCalendar recurrence rules.
All methods expecting dates as parameters accept all values that the Horde_Date constructor accepts, i.e. a timestamp, another Horde_Date object, an ISO time string or a hash.
