Holiday Announcement

My company has a general announcement that plays when a call comes in. For the holiday, we would like to change that message to a holiday recording telling our customers that we are closed for a week. I have recorded the message but I am lost on what to do to activate the new holiday greeting and dimiss the general one until after the holidays. Can anybody help?

Applications > Time Conditions

Time condition name: Holiday Greeting
Time Group: (Name of your holiday time group).
Destination if time matches:

Select the announcement.

Make sure you have a destination on the announcement too depending on what you want to do (message box, hang up, etc.)
