You can set the repeat frequency as daily, weekly, monthly by day (for example every Monday of first week), monthly by date (for example 25th of every month), yearly by day (for example every Monday of first week of October) and yearly by date, to a calendar entry. </p> <p>A repeat rule can be set by passing a <xref href="GUID-010934C4-DC1F-37F3-8121-E497B0BC9CDE.dita"><apiname>TCalRRule</apiname></xref> to <xref href="GUID-725D11A2-8805-3466-98DB-EF5CDEAF2801.dita#GUID-725D11A2-8805-3466-98DB-EF5CDEAF2801/GUID-C66CEE4B-6B7C-3AA4-896F-AE3724C915E2"><apiname>CCalEntry::SetRRule()</apiname></xref>.
