Well, the measurement doesn't have to be in inches or anything. It just has to be the same so that the cells are equal in size. You should be able to print out 6 months at a time. If you are familiar with word then the font sizes and characteristics (bold, underline, etc) should be a snap. If you right click on a cell and click Format Cell then you can color the cells, places borders, etc. Here is a sample for the first 6 months. You should be able to copy this entire sheet and make the latter of the year yourself. This only takes a few minutes once you practice a little.
