13-Month Ruled Calendars
Modeled after the Ruled Calendars, this version has 13 months and an empty header space in the upper left hand side where you can write a title - by hand. The 13-Month calendar is available starting in the months of January, May, June, July, August, and September. If you need a different starting month from those here, use the 13-Month Custom Calendar that my son made.
The 13-Month Ruled Calendar may also be used as a personal calendar, birthday & anniversary calendar, etc.

On Donna Young's Site CD this calendar is is available up to the school year of 25-26. I also included an XLS file so that, if you can open XLS files, you can choose any starting month and year to make your 13-month school calendar.
