Time of Day
It is ideal to have the bris in the morning, showing one's desire to perform the commandment as soon as possible. However, anytime of day before sundown is acceptable. During the summer when sundown is much later in the day, many people prefer to make the bris after work hours so that more friends and family can attend.
Rabbi Asa tries to accommodate everyone's schedule. However, the bris is scheduled on a first come, first serve basis and sometimes there are multiple brises taking placing the same day. It is best to call the mohel as soon as possible after the baby is born to reserve the desired time of day.
