When does one begin to count the seven days?

Q 1: If I receive a newborn baby after the Maghrib (sunset) Prayer, how do I count seven days? Or when exactly do two days separate from each other every night? Please provide me with an explanation of this issue.

A 1: The day starts from the time of the second daybreak, which is Al-Fajr-ul-Sadiq (true dawn) until sunset. The concerned night belongs to its following day except the night of the Day of Nahr (Sacrifice, 10th of Dhul-Hijjah, when pilgrims slaughter their sacrificial animals) which belongs to the Day of `Arafah (9th of Dhul-Hijjah) under the ruling of Hajj.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
