Calendar Project (easy fix)

dagurr (16)
How do I get this code to work in a way that looks like a calendar. I have tried but it doesnt look right. The first week is always off i need help plz.
It displays moving the program to the right too much. When offset is put.
It has the appearance of a calendar and just has one tiny error

Here's your calendar program. Just a few very small errors, that were easy to correct. I commented the code to show what I did.
