Trigger Lights Off with Google Calendar Event
Use this to create a vacation lighting schedule in conjunction with another of my Applets called "Trigger Lights On with Google Calendar Event". Create the calendar events easily with the Do Note called "Quickly create events in Google Calendar". Just type or say "Turn lights off at 11pm on July 25th", or whatever time and date is desired. Lights will actually go off about 15 minutes after the event.
