Calendars are needed from time to time in presentations. Here is a set for 2013 that can be colored to match your template colors. All of the fields in the calendars are eligible for fill and line colors.
These calendars are also set up without text. All of the days of the weeks and the dates are graphics, which means you can size the monthly group to any size you want and not have to worry about resizing the text.
