הלכה אויף שמות 35:22

The Temple is not to be built at night as it says "and on the day the Tabernacle was erected," i.e. we erect it during the day but not at night. We may work on the construction from dawn until the stars come out, and everyone is obligated to build helping physically and financially both men and women just like the sanctuary in the desert. However, we do not close the schools in order [for the children] to build the Temple nor does building the Temple override Shabbat or the festivals.
