You add a calculated date to specify a recurring event, such as Friday of the first week of even months. Calculated dates are also used for events or holidays that do not always fall on the same date each year.
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, to behave differently for the whole month of January.
