Since ancient times, Sunday has been a day in which pagans, witches, shamans, and other occult and spiritualistic peoples worshipped the sun, hence the name--Sun-day.
Lakini haijapata siku zote kuwa hivyo! Tangu nyakati za zamani, Jumapili imekuwa siku ambayo wapagani, wachawi, waaguzi, na watu wengine wanaojihusisha na uchawi na umizimu waliabudu jua, na ndiyo maana tuna jina – Sun-day [Siku ya Jua].
