The traditional Nso eight-day calendar for the Nso people of Cameroon.
Ya Nso' — Yanso is a free, open-source calendar app that brings the traditional timekeeping of the Nso people of Cameroon to your phone. The Nso calendar runs on an eight-day week — a cycle of Kaavi, Rəəveiy, Kiloovəy, Nsəəri, Geegee, ŋgoilum, Waiylun, and Ntaŋrin — that has shaped daily life in Nso land for generations. Yanso lets you see today's Nso date alongside its Gregorian equivalent, so you always know where you stand in the traditional cycle. FEATURES • Today's Nso date — instantly see the current day in the eight-day Nso week and the corresponding Lamnso month. • Month view — an eight-column calendar grid showing the full Nso and Gregorian month side by side. • Year view — all twelve Lamnso months at a glance, with quick navigation to any month. • Rest days highlighted — traditional rest days (Kiloovəy and ŋgoilum) are marked in every view so you never miss them. • Market day highlighted — Kaavi, the principal market day when everyone gathers at the Mbvə' market in Kimbo' (Kumbo), is clearly indicated. • Twelve Lamnso months — Mfiilum, Kifir, Kiŋmgbù ke wuu, Vishévti, Ma'an san, Ma'an saar, Ntoòbiŋ, Tònŋkin, ŋkivin, Verə̀mrə̀m, Sán, and Ntinen Saar. • Light and dark themes — a hand-crafted design inspired by kola-nut brown, kente gold, terracotta clay, and indigo raffia. • Fully offline — no internet connection required, ever. • No ads, no accounts, no data collection. CULTURAL ACCURACY Yanso treats accuracy as a core principle. Every piece of cultural data carries a verification status, and the project publishes its research sources openly. The app will never present uncertain information as established fact. OPEN SOURCE Yanso is completely open source. The calendar engine, the cultural data, and the app itself are all available on GitHub for anyone to inspect, contribute to, or build on. If you have a cultural correction, a verified calendar date, or local knowledge to share, your contribution is welcome. Preserve the past. Understand the present. Pass it on.
