Panchangam is a traditional Hindu calendar that provides essential information about the lunar and solar cycles. It includes five key elements: Tithi (lunar day), Vaar (day of the week), Nakshatra (lunar mansion), Yoga (a specific combination of the sun and moon), and Karana (half of a Tithi). These elements help in determining auspicious times for various activities, such as weddings and festivals. The Panchangam is widely used in India and is essential for astrology and religious observances. It is often consulted by priests and individuals to plan important events according to favorable timings, ensuring alignment with cosmic energies.
