Muḥarram (Arabic: مُحَرَّم) is the first month of the Islamic calendar. It is one of the four sacred months of the year during which warfare is forbidden. It is held to be the second holiest month, after Ramaḍān. Since the Islamic calendar is a lunar calendar, Muharram moves from year to year when compared with the Gregorian calendar.
The tenth day of Muharram is known as the Day of Ashura, part of the Mourning of Muharram for Shia Muslims and a day of fasting for Sunni Muslims. The practice of fasting during Ashura stems from the hadith that Musa (Moses) and his people obtained a victory over the Egyptian Pharaoh on the 10th day of Muharram; accordingly Muhammad asked Muslims to fast on this day and on the day prior, the Day of Tasu'a.
Shia Muslims mourn the death of Ḥusayn ibn ʿAlī and his family, honoring the martyrs by prayer and abstinence from joyous events. Shia Muslims do not fast on the 10th of Muharram, but some will not eat or drink until zawal (afternoon) to show their sympathy with Husayn. In addition there is an important ziyarat book, the Ziyarat Ashura about Husayn ibn Ali. In the Shia sect, it is popular to read this ziyarat on this date.
Muharram and Ashura
The sighting of the new moon ushers in the Islamic New Year. The first month, Muharram, is one of the four sacred months mentioned in the Quran, along with the seventh month of Rajab, and the eleventh and twelfth months of Dhu al-Qi'dah and Dhu al-Hijjah, respectively, immediately preceding Muharram. During these sacred months, warfare is forbidden. Before the advent of Islam, the Quraish and Arabs also forbade warfare during those months.
Muharram and Ashura to the Shia
Muharram is a month of remembrance and modern Shia meditation that is often considered synonymous with Ashura. Ashura, which literally means the "Tenth" in Arabic, refers to the tenth day of Muharram. It is well-known because of historical significance and mourning for the murder of Ḥusayn ibn Ali, the grandson of Muhammad.
Shia's begin mourning from the first night of Muharram and continue for ten nights, climaxing on the 10th of Muharram, known as the Day of Ashura. The last few days up until and including the Day of Ashura are the most important because these were the days in which Husayn and his family and followers (including women, children and elderly people) were deprived of water from the 7th onward and on the 10th, Husayn and 72 of his followers were killed by the army of Yazid I at the Battle of Karbala on Yazid's orders. The surviving members of Husayn’s family and those of his followers were taken captive, marched to Damascus, and imprisoned there.
Timing for Muharram
The Islamic calendar is a lunar calendar, and months begin when the first crescent of a new moon is sighted. Since the Islamic lunar calendar year is 10 to 11 days shorter than the solar year, Muharram migrates throughout the solar years. The estimated start and end dates for Muharram are as follows (based on the Umm al-Qura calendar of Saudi Arabia:)
|AH||First day (CE / AD)||Last day (CE / AD)|

Then, the pilgrim will be robbed in (the month of) Dhu al-Hijjah. Then, the prohibitions will be violated in (the month of) al-Muharram.
