How should one cut his nails and when may he not cut his nails during the weekdays?
Answer:
Some are careful not to cut the nails of two adjacent fingers together (this is ruled by Shulchan Aruch, although Arizal wrote that it is permitted). It is permitted to cut nails on weekdays, with the exception of chol ha-mo’ed. Some are careful not to cut nails at night.
