+### Values for Nth day of the Month

+For example, if you want to have an schedule for the 2nd Saturday of the months, create an extra Tag Key definition called **Saturday2**
+
+A specific Nth day of month schedule overwrites a normal day of the month schedule. So a **Saturday2** overwrites a **Saturday** schedule.
