The Rule of Time is both a universal monthly calendar and a ruler.
The star, positioned on the crenellated upper edge, marks the day and date. Rolling the star allows you to change the day and also find future dates and days of the current month.
The dates are positioned every centimeter: the Rule of Time thus becomes a graduated rule.
