Ethiopia
Most of Ethiopia's population is Christian, so Christmas is often accompanied by large gatherings and celebrations. Ethiopia recognizes the Gregorian calendar, but officially follows the Ethiopian calendar. This means that Christmas is not celebrated at the same time as most countries in the world. Ganna, the Ethiopian Christmas holiday, occurs on January 7th in the Gregorian calendar. When the Ethiopians begin the Prophet's Fast on November 25th, preparations for Gannah begin, and they stick to a strict vegan diet of just one meal a day.
For Gannas, people wear white garments called 'Netera', which are similar to shawls. On the night before Gannas, they attend prayers from 6:00 pm to around 3:00 am. Twelve days after Ganna begins a three-day festival called 'Timkat' starts on January the 19th and celebrations include church services, street processions, and music. Holidays are not commoditised, and no gifts are given as the holiday focuses more on community, family, and religion.
