On his long way home, Ganesha accidentally dropped all of his ladoo or laddu, a sweet Indian treat or candy. As he was gathering his favorite food from the ground, he heard roars of laughter from the moon. Angry at the moon, Ganesha punished the moon that once shone brightly every night by causing it to wane each month. Watch Ganesha and Why the Moon Waxes and Wanes.
In Hinduism, there are different celebrations and times of remembrance that correspond to the lunar calendar. Unlike the months we are familiar with in the U.S. (e.g., January, February, March, etc.), the months in the lunar calendar begin and end based on the monthly cycle of the moon phases. While we most commonly use the Gregorian calendar to tell what day it is, the lunar calendar helps us identify when to observe holidays, rituals, and festivals. Holi, for instance, is the Spring Festival of Colors and takes place on the full moon day in the month of Phalgun (late February to late March).
In this activity, observe the different moon phases, learn about the lunar calendar, and research some Hindu traditions and celebrations.
