Q. re changing title image by date

[Old-Git]

Does anyone know of a mod that will allow me to change the title image on mysite on specified dates. What I want to do is have the title image change to something a little different, say every July 4th it's rotate in a new image with fireworks on it, on remembrance Sunday it'll rotate in an image with a poppy on it. But I also want to specify how long it remains in place until it reverts to the main title image, e.g. I might want an Xmas title image to remain for the 10 days of xmas before reverting to the normal title image.

Is there anything like that anywhere, I've had a search in the 4x Mods sub-forum but nothing is leaping out at me, of-course I've also got a really bad head cold so I might have just missed it!
