I just love yoga, I chose to do it once a week on Tuesdays.
According to most calendars, that's the 3rd day of the week, with the week starting on Sunday.  But I think many of us see it as the 2nd day of the week.
I think so too, nowadays week usually starts on Monday. And Yoga is so relaxing, perfect for beginning of the week.
Yoga
Yoga (; ; ) is a group of physical, mental, and spiritual practices or disciplines which originated in ancient India. Yoga is one of the six orthodox schools of Hindu philosophical traditions. There is a broad variety of yoga schools, practices, and goals in Hinduism, Buddhism, and Jainism. The term "yoga" in the Western world often denotes a modern form of Hatha yoga, yoga as exercise, consisting largely of the postures called asanas.
The origins of yoga have been speculated to date back
in Los Angeles but achieved little attention elsewhere. "Nowadays Clancy Can't Even Sing" was listed at number 110 on the "Billboard" charts on August 20 before disappearing just a week later. On the single's lackluster commercial performance, Furay later suggested "Nowadays Clancy Can't Even Sing" was "too deep" and "too ambitious" of a choice for the A-side, and considered "Do I Have to Come Right Out and Say It" and "Sit Down I Think I Love You"
