No particular theme for the monthly desktop calendars this year (so far), but if you have a suggestion, I'd love to hear it!
At any rate, here's your new calendar to bring in 2013. Click to expand the image to full size, right-click and choose Set as Wallpaper or Background.
To really make the calendar "pop" right-click on your background and choose black.
I'll be back in a few - in the meantime, enjoy your desktop calendar, and accept my best wishes for a happy and prosperous New Year!
