[wp-hackers] Switching theme depending time of the year

[Daniel Fenn]

Hello all,

Bit late but merry xmas and happy new year to you all.

I would like to know if there any way that I can have say 3 themes
installed on a wordpress blog and have a script that will change the
theme used depending on what time of the year it is or even down to
what day it is. Does anyone know how I can do that?

Thankyou :)
