Abstract
This calendar-grader can be manufactured in any material suitable for its use and size; wall, table or pocket. The relationship of encounters in the lower part and the two squares in the upper one can be suppressed. The exclusive mechanism is the numbered score tapes combined to the special dissection of the rest of the calendar of days. (Machine-translation by Google Translate, not legally binding)
