The Oromo calendar is a calendrical system developed by the Oromo around 300 BC. A lunar-stellar calendar, it relies on astronomical observations of the moon in conjunction with seven particular stars or constellations. Oromo months (stars/lunar phases) are Bittottessa (Iangulum), Camsa (Pleiades), Bufa (Aldebarran), Waxabajjii (Belletrix), Obora Gudda (Central Orion-Saiph), Obora Dikka (Sirius), Birra (full moon), Cikawa (gibbous moon), Sadasaa (quarter moon), Abrasa (large crescent), Ammaji (medium crescent) and Gurrandala (small crescent).[1]
