The 2018 Hatha Yoga Calendar references a Panchangam for Portland, Oregon. A typical Panchāngam may state tabulations of positions of the sun, moon, and other planets for every 
day of the year on a fixed place (longitude, latitude) and time of day (in 24-hour format IST). The users calculate the remaining data using their relative difference from th
is fixed place and time.

Yogis use an Indian astrology system of calculation (rather than a simple astronomy calculation). In this system, it is the period of time prior to the point the moon becomes exactly new/full that is considered as the ‘moon day’ (called a tithi in Indian Astrology). Further more, in this system, the day is considered to begin at sunrise rather than mid-night.

In India, where yoga comes from, the term ‘moon day’ is a loose translation of the Sanskrit term ‘tithi,’ and would be more accurately translated as ‘lunar phase’ rather than ‘moon day.’ Each tithi is the time period it takes for the the moon to traverse 12° in the sky thus making 30 tithis (or lunar phases) per lunar cycle. These tithis begin at varying times of day and actually vary in duration from approximately 19 to 26 hours. What loosely gets termed the full and new ‘moon days’ are actually the 15th and the 30th tithis of this Indian Astrology (Jyotish) system.
