Bonus (Optional): Although many societies base their calendars on the movements of the sun or the moon, a calendar's starting date is often linked to cultural or religious traditions. For example, both the Muslim and the Hebrew calendars are based on the phases of the moon, but they differ in a number of significant ways. Research a calendar used by another culture and find out the cultural significance of the calendar's starting date, the number of days per month, and the number of days per year. Write a short paragraph to explain your findings.
