"Kindergärten" can be open from 7 a.m. to 5 p.m. or longer and may also house a "Kinderkrippe", meaning crèche, for children between the ages of eight weeks and three years, and possibly an afternoon "Hort" (often associated with a primary school) for school-age children aged 6 to 10 who spend the time after their lessons there. Alongside nurseries, there are day-care nurses (called "Tagesmutter", plural "Tagesmütter" – the formal, gender-neutral form is "Tagespflegeperson(en)") working independently from any pre-school institution in individual homes and looking after only three to five children typically up to three years of age. These nurses are supported and supervised by local authorities.
