Raspberry Pi 3D Christmas Tree

I found a nice little Christmas tree on ThePiHut which has 25 individually controlled LED's, 24 read ones and 1 white as the star on top. There is both a pre-soldered and a DIY kit. The pre-soldered one uses SMD LED's while the DIY kit uses normal 3mm LED's.

The example script provided (as can be seen below) is a nice starting point. It makes all 25 LED's flicker. This is nice, but I wanted to make it a bit more automated then just that.

from gpiozero import LEDBoard
from gpiozero.tools import random_values
from signal import pause
tree = LEDBoard(*range(2,28),pwm=True)
for led in tree:
 led.source_delay = 0.1
 led.source = random_values()
pause()

I have been playing around with it and had the following idea:
There are 25 days in December until Christmas. This would be nice to then have each day, starting from the 1st of December, to have one LED light up (flickering). Then on the 25th the star will light up.
So I started playing around with that idea and came up with the script below. It will give a glowing effect on the star LED before the 1st of December. On the 1st of December LED nr 1 will light up. Then the following day nr 2, etc. On Christmas day the 25th of December the star will light up (but won't flicker).

The script can also be found at: Wijman GitLab - 3D Christmas Tree

This script does depend on the Raspberry Pi to have its clock set correctly.
