A panchāngam (Tamil: பஞ்சாங்கம், Sanskrit: pañcāṅgam, Malayalam: പഞ്ചാംഗം) is a Hindu astrological almanac, which follows traditional Indian cosmology, and presents important astronomical data in tabulated form. It is sometimes spelled Pancanga, Panchanga, Panchaanga, or Panchānga, and is pronounced Panchānga. Pachangas are used in Jyotisha (Jyotiṣa).
