The dates specified in a calendar are shown in the date list. You can specify dates in a calendar by three different methods:
Date: a specific date
Date range: a fixed period with a set start and stop date
Calculated date: a fixed period that repeats
A single date within a calendar is an entry that occurs once or every year on the same date.
The following single date entry choices schedule an event on a single date, January 1, 2009:
Year - 2009
Month - January
Day of month - 1
Day of week - Any day
The following single date entry choices schedule an event on a single date every year, January 1:
Year - Any Year
Month - January
Day of month - 1
Day of week - Any day
The following choices produce an error message:
A day, month, and year combination that does not coincide
An example is Friday, March 5, 2009. This date actually falls on a Thursday.
Any years past 2105
An explicit day that is out of range
An example is September 31 or February 29 in a non-leap year.
You can include a date range in the date list. A date range is a series of days to include in a calendar. An example of a date range is January 1, 2009 to January 31, 2009, which adds the entire month of January to the calendar as an event. You can use this date range for a device, such as a thermostat or a detector, to behave differently for the whole month of January.
You can include a calculated date on a date list. A calculated date has no set start and stop date. For example, you use a calculated date to schedule the first week of the even months on a Friday.
