"Help Me with My Dream Please".

I have a dream...the 12 Days of Christmas carried out with 12 artificial trees in my front yard. I have the trees about ready .... Mostly throw offs from neighbors. A few I have restring with led lights and a few I've just added lights to dead sections. I've worked out the spacing in my front yard ... Even how to keep them in place during windy times....

Now for the challenge. How do I get the twelve days of Christmas lights to shine at the right time on each tree...is it even possible?

Thanks y'all in advance!!
