This is my first try of a real mIRC script!
I did not copy and paste it from another snippet.

Leave any comments on how to improve.

How to use:

Go to Commands -> Days Until Christmas

OR

Right clicking on your channel window and pressing Days until Christmas.
Both of them produce the same output so it doesn't matter
