The Sabbath is celebrated from sundown on Friday to sundown on Saturday.  The rituals and customs surrounding the Sabbath were crucial to Crypto-Jewish culture because their celebration did not require a synagogue or community of people, which lent itself well to the covert nature of Jewish practice at the time.  Sabbath customs strongly stress cleanliness; in preparation for the Sabbath, many crypto-Jews would bathe on Friday afternoons and put on clean clothes afterwards.  Crypto-Jews would clean the house in preparation for the Sabbath as well; the two most common activities were sweeping the home and applying clean linen.  Crypto-Jews strictly abstained from any type of work once the Sabbath began, thus all of these preparations had to have taken place Friday morning or afternoon; for example, all Sabbath meals had to be prepared Friday night.  Foods that could be left in a pot over the fire overnight, such as stews, were popular foods.   The Saturday of Sabbath, especially the morning, was dedicated to prayer, either individual or communal; Saturday afternoons and evenings were commonly spent visiting relatives and friends.

Se celebra el sábado entre la puesta del sol del viernes hasta la puesta del sol del sábado.  Los rituales y costumbres del sábado eran cruciales para la cultura de los cripto-judíos porque su celebración no requería una sinagoga o una comunidad de gente, algo que convenía las manera ocultas de la religión judía de esta época.  Los costumbres del sábado enfatizan la limpieza; en preparación para el sábado los cripto-judíos se bañaban por la tarde del viernes, y después se vestían de ropa limpia.  Cripto-judíos también limpiaban la casa en preparación para el sábado; las dos actividades más comunes eran barrer y poner ropa limpia en la cama y la mesa.  Los cripto-judíos se abstenaban estrictamente de todo tipo de trabajo durante el sábado, entonces era necesario preparar todo—incluso la comida—antes de su comienzo.
