Paush Purnima in 2026 will be observed on January 3rd, following the Hindu calendar's Udaya Tithi principle, though the Purnima tithi begins on January 2nd. This auspicious full moon day is significant for holy baths, charity, and spiritual rituals aimed at cleansing sins, promoting peace, and restoring balance. Devotees worship Lord Vishnu and Chandra Dev, with specific planetary remedies and donations suggested for various aspects of life, including career and emotional well-being.
