The Berber calendar is the agricultural calendar that is traditionally used in North Africa regions. It is also known in Arabic as the ﻓﻼﺣﻲ fellāḥī "rustic" or ﻋﺠﻤﻲ ʿajamī "foreign" calendar. It is employed to regulate the seasonal agricultural works, in place of the Islamic calendar which, being of lunar type, without any relation with the seasonal cycles, is useful to calculate religious festivals but ill-adapted for agriculture.

The Berber calendar, a legacy of Roman Mauretania, is a surviving form of the ancient Julian calendar (with month names derived from the Latin) which was used in Europe before the introduction of the Gregorian calendar, and which is also still in use in the Eastern churches.

There have been other indigenous calendars among the Berber peoples in the past, for example that of the Guanches of the Canary Islands, but relatively little is known of these.

Not much is known about the division of time among ancient Berbers. Some elements of a pre-Islamic, and almost certainly pre-Roman, calendar emerge from some medieval writings, analyzed by Nico van den Boogert. Some correspondences with the traditional Tuareg calendar suggest that in antiquity there existed, with some degree of diffusion, a "Berber" time computation, organized on native bases.

Anita Berber (10 June 1899 – 10 November 1928) was a German dancer, actress, and writer who was the subject of an Otto Dix painting. She lived during the Weimar period.

Born in Leipzig to musician parents who later divorced, she was raised mainly by her grandmother in Dresden. By the age of 16, she had moved to Berlin and made her debut as a cabaret dancer. By 1918 she was working in film, and she began dancing nude in 1919. Scandalously androgynous, she quickly made a name for herself. She wore heavy dancer's make-up, which on the black-and-white photos and films of the time came across as jet black lipstick painted across the heart-shaped part of her skinny lips, and charcoaled eyes.

Her hair was cut fashionably into a short bob and was frequently bright red, as in 1925 when the German painter Otto Dix painted a portrait of her, titled "The Dancer Anita Berber". Her dancer friend and sometime lover Sebastian Droste, who performed in the film Algol (1920), was skinny and had black hair with gelled up curls much like sideburns. Neither of them wore much more than lowslung loincloths and Anita occasionally a corsage worn well below her small breasts.
