The Calendar Microworld is for visualizing the calendar of every month of the year and for marking periods of time (days) of different length to represent situations referred to time-related problems (problems about time passed, intervals of days, etc.).
In this Microworld it is possible: to visualize the calendar of every month of the year, to trace one or some spaces of time within the calendar of every month, fixing a steady interval since a day established by the user (space of one day, of two days, etc.). It is also possible to trace one or some intervals between two days established by the user within the calendar of every month.

The representations realized in the Calendar Microworld can be copied to be pasted on the Solution Sheet.
