The Islamic Calendar and Sacred Months
Learn about the Hijri calendar and the significance of Islamic months.
The Islamic calendar, also known as the Hijri calendar, is based on lunar cycles and includes sacred months with special significance in Islamic tradition. This calendar was established during the time of the second Caliph, Umar ibn al-Khattab, and begins from the year of the Prophet's migration (Hijrah) from Mecca to Medina in 622 CE. The Islamic calendar is used by Muslims worldwide to determine religious observances and important dates.
The Islamic calendar is purely lunar, meaning it's based on the cycles of the moon rather than the sun. A lunar month is approximately 29.5 days, and an Islamic year consists of 12 lunar months, totaling about 354 or 355 days. This is about 11 days shorter than the solar year, which means Islamic months shift through the seasons over time.
The twelve months of the Islamic calendar are: Muharram, Safar, Rabi' al-Awwal, Rabi' al-Thani, Jumada al-Ula, Jumada al-Thaniyah, Rajab, Sha'ban, Ramadan, Shawwal, Dhul-Qi'dah, and Dhul-Hijjah. Each month begins when the new moon is sighted, which is why the exact start of each month can vary slightly by location.
Ramadan is the most well-known Islamic month, during which Muslims fast from dawn to sunset. It's the month in which the Quran was first revealed to Prophet Muhammad (peace be upon him). Ramadan is a time of increased worship, reflection, charity, and community bonding. The sighting of the new moon marks the beginning of Ramadan and the end of the previous month.
Dhul-Hijjah is the month of Hajj (pilgrimage). The first ten days of this month are particularly sacred, and the Day of Arafah (9th of Dhul-Hijjah) and Eid al-Adha (10th of Dhul-Hijjah) are among the most important days in the Islamic calendar.
The four sacred months (Al-Ashhur al-Hurum) are Muharram, Rajab, Dhul-Qi'dah, and Dhul-Hijjah. During these months, fighting was traditionally prohibited in pre-Islamic Arabia, and this prohibition was confirmed in Islam. These months hold special significance, and good deeds performed during them carry extra reward.
Muharram is the first month of the Islamic year and includes the Day of Ashura (10th of Muharram), which has special significance. The Prophet (peace be upon him) recommended fasting on this day, and it commemorates various important events in Islamic history.
Understanding the Islamic calendar helps Muslims plan their religious observances, know when to fast, when to perform Hajj, and when important Islamic events occur. It also helps Muslims maintain connection with the global Muslim community, as Muslims worldwide follow the same calendar for religious purposes.
The lunar calendar creates a different rhythm of life compared to solar calendars. Islamic months don't correspond to seasons, so Ramadan, for example, occurs at different times of the year over a 33-year cycle. This variation means that Muslims experience fasting during different seasons throughout their lives.
Learning about the Islamic calendar and its months deepens understanding of Islamic timekeeping and helps Muslims appreciate the wisdom in using a lunar calendar for religious purposes. It connects Muslims to their history, as the calendar dates from the foundational event of the Hijrah, and helps maintain unity in the global Muslim community.
