The Months settings are used in the Advanced Recurring Options for daily, weekly, monthly and yearly events to specify valid months an event should occur. For daily, weekly, and monthly events, all months are selected by default. Event occurrences can be restricted to specific months by selecting only those months. For Yearly events, only the month of the event start date is selected by default. The event can be set to occur in additional months during the year by selecting those months.
The Show All and Show None buttons can be used to quickly toggle all months on and off.
