The Sidama nation has its own New Year celebration which will be celebrated for two weeks colorfully every year. The holiday is known by the name of Fiche. The Fiche day will be clearly identified through the Ayantos (the traditional astrologists). The Ayantos will spot the day in advance through observing the stars and notify to the clan leaders. Fiche is the most celebrated Sidama cultural holiday, representing the Sidama New Year. The Fiche is based on the lunar system. Sidama elders (astrologists) observe the movement of the stars in the sky and decide the date for the New Year and the Fichche celebration. The Sidama New Year is therefore is unique in that it does not have a fixed date. It rotates every year following the movements of the stars. Sidama has 13 months in a year. And each of the months is divided equally into 28 days while the 13th month has 29 days. This is because the Sidama week has only 4 days and hence each month has 7 weeks instead of the conventional 4 weeks. The names of the 4 days in Sidama week are called: Dikko, Deela, Qawadoo and Qawalanka to be followed by Dikko completing the cycle of a 4-day week
