It is the first month of the Islamic Calendar.
The meaning of the word:- The word "Muharram" means "Forbidden." Even before Islam, this month was always known as a scared month in which all unlawful acts were forbidden, prominently the shedding of blood.
A blessing of Muharram:- There are many bounties of this month, especially the tenth of Muharram.
Two of the many virtues of the 10th of Muharram:
-In this day he who spends more lavishly for the sake of his family members, Allah Taala will bestow blessing upon the sustenance of the following year.
Abu Qataada has related that the Prophet has reported to have said, It is my thought that by fasting on the 10th of Muharram Allah Taala will pardon the sins of the past year. (Tirmizi)
