According to the Oromoo Dhahaa-Oromo Calender, September 30, 2012 is the annual Thanksgiving day-Irreechaa Birraa of the year. An Irreechaa Birraa is a celebration that repeats once in a year-in birraa and involves special activities or amusements. It has a lot of importance in our lives.
We celebrate Irreechaa to thank Waaqaa for the blessings and mercies we have received throughout the past year at the sacred grounds of Hora Harsadi (Lake Harsadi), Bishoftu, Oromia.
The Irreechaa festival is celebrated every year at the beginning of Birraa (the sunny new season after the dark, rainy winter season) throughout Oromia and around the world where Diaspora Oromos live.
We celebrate Irreechaa not only to thank Waaqaa (God) also to welcome the new season of plentiful harvests after the dark and rainy winter season associated with nature and creature. On Irreechaa festivals, friends, family, and relatives gather together and celebrate with joy and happiness. Irreechaa Festivals bring people closer to each other and make social bonds.
We celebrate Irreechaa festivals to follow our tradition and religion in society.
