In some yoga practices it is recommended you do not practice on either a full moon or new moon because the energy of how the moon and sun are aligned can either be too grounding or too uplifting. Personally, I don't schedule my practices around the moon cycles, but I do believe there is some truth to it. Here is a link to an good summary from Ashtanga Yoga http://www.ashtangayogacenter.com/moon.html.
So...the new moon is scheduled for march 15th and the full moon for march 29th. I'm curious to see what happen :)
