How to set temporary Holiday greeting

Hello everyone this is my first post. I’d like to know the easiest way to set a temporary Holiday greeting. I know how to record the announcement and set the Timing Group but I need the next steps to set the greeting so it plays only during the time specified in the Timing Group.For example, I’d like a message to play starting at 5:00 PM stating that we will be closed Monday for the Holiday. I would like this message to play until Monday morning at 7:00 AM and then go back to our regular announcement. How do I do this?

That would be explained in detail in the FreePBX wiki under time groups and time conditions.

I see how to set the times up, but where do I select the correct message to play during the time group/condition?

Under time condition you set a destination, which can be an announcement, ivr, etc.
