The Kohinoor Calendar is a traditional Odia Panjika (almanac). Unlike standard Western calendars, it calculates time using the lunar cycle and ancient Hindu astrological texts.

The top of each page usually lists the Gregorian month (e.g., January 1988), while the main body is divided into columns tracking the Odia months like Pousha , Magha , Phalguna , and Chaitra . Symbols like a full circle represent Purnima (Full Moon), while a shaded circle represents Amavasya (New Moon).

The 1988 Ashwin month featured the major worship of Goddess Durga in late October.
