The Odia calendar (Odia: ପାଞ୍ଜି Pāñji) is a solar calendar used by the Odia people from the Odisha region of the Indian subcontinent. The calendar follows the sidereal solar cycle while using the lunar Purnimanta phase for the religious dates.[1] The New Year in the Odia calendar is known as Maha Bishuba Sankranti or Pana Sankranti. It occurs on the first day of the traditional solar month of Meṣa (Georgian: Aries), hence equivalent lunar month Baisakha (odia: ବୈଶାଖ). The Odia calendar follows the Utkaliya era, which began on Bhādra śukla dvādaśī from 592 CE.[2]
