Moon days 

There are no Ashtanga classes on the days of full moon and new moon.

Because human beings are 70% water, we are affected by the moon’s gravitational pull at  different times of the month. The influence of the moon can be felt more strongly on Full and New Moon days. On these days it is advised to take rest from practice.  Practicing asana and meditation over time makes us more attuned to these natural cycles. Full and New moon days are observed as rest days in the Ashtanga Yoga tradition.
