Working on a theme & need a few things I can't figure out.

1. What is the max size to have icons fit together covering the width of the wallpaper? I tried 320 divided by 5 which would be 64 but when I do this there is a 2 pixel space on the left side of the screen & the icons overlap. I want 5 icons to fit perfectly together creating the image.

2. I'm looking for a date widget that will sit between the clock & battery on the status bar. Prefer it to be in this format 4/5 or 4/05 simple.
