While modern printed Panchangams rely heavily on mathematical models (Tantra and Ganitha), the uses a unique, ancient memory-based system called the Vakya method—meaning "sentence" or "phrase." These are mnemonic verses passed down through oral tradition, often attributed to the sage Kalidasa and later refined by astronomical masters like Makarakesa Yajvan . : It is based on the Vakya (meaning
