Berber calendar have begun computing the years starting from 950 BC, the approximate date of the rising into power of the first Libyan Pharaoh in Egypt, Shoshenq I, whom they identified as the first prominent Berber in history (he is recorded as being of Libyan origin). For example, the Gregorian year corresponds to the year of the Berber calendar. This innovation has been adopted with conviction by many supporters of the Berber culture and is now a part of the cultural heritage of this people, fully integrated in the system of traditional customs related the North-African calendar.

Proto-Berber language are the only Berber languages to preserve Proto-Berber *β as β; elsewhere in Berber it becomes "h" or disappears. The Proto-Berber consonantal system reconstructed by Allati (cf. Allati, 2002, 2011) is based on remains from the ancient stages of this language preserved in the ancient toponymical stratas, in Libyan inscriptions and in the modern Berber varieties. It had stops b, t, d, k, g; fricative s; nasal n and liquids l, r. The stops of the phonological system have evolved since the proto-Berber stage into variants from which other consonants have been progressively formed (Allati, 2002, 2011). Karl G. Prasse
