An astrological notebook called Panchang, often known as "Five Limbs (parts)," provides useful information that an astrologer needs. Tithi (lunar day), Yoga (luni-solar day), Vara (weekday), Nakshatra (constellation), and Karana are the five limbs that make up this system (half of a lunar day.) In essence, it is a Hindu calendar based on heavenly body positions. The panchang can predict the lucky times for marriage, key ceremonies, and other events.
