Islamic calendar
Being a purely lunar calendar, it is not synchronized with the seasons. With an annual drift of 11 or 12 days, the seasonal relation repeats about every 33 Islamic years.
The Islamic months are named as follows:[3]
- Muḥarram — المحرّم — means “forbidden” in Arabic, so called because it was unlawful to fight during this month. Muharram is the second most sacred Muslim month, and includes the Day of Ashura.
- Ṣafar — صفر — means “void” in Arabic, supposedly named because pagan Arabs looted during this month and left the houses empty.
- Rabīʿ I (Rabīʿ al-Awwal) — ربيع الأوّل — means “the first Spring” in Arabic.
- Rabīʿ II (Rabīʿ ath-Thānī or Rabīʿ al-Ākhir) — ربيع الآخر , ربيع الثاني — means “the second (or last) Spring” in Arabic.
- Jumādā I (Jumādā al-Ūlā) — جمادى الأولى — means “the first month of parched land” in Arabic.
- Jumādā II (Jumādā ath-Thāniya or Jumādā al-Ākhira) — جمادى الآخرة , جمادى الثانية — means “the second (or last) month of parched land” in Arabic.
- Rajab — رجب — means “respect” or “honor” in Arabic. Rajab is another of the sacred months in which fighting was traditionally forbidden.
- Shaʿbān — شعبان — means “scattered” in Arabic, marking the time of year when Arab tribes dispersed to find water.
- Ramaḍān — رمضان — means “scorched” in Arabic. Ramadan is the most venerated month of the Hijri calendar, during which Muslims fast between sunrise and sunset.
- Shawwāl — شوّال — means “raised” in Arabic, as she-camels begin to raise their tails during this time of year, after giving birth.
- Dhū al-Qaʿda — ذو القعدة — means “the one of truce” in Arabic. Dhu al-Qa’da was another month during which war was banned.
- Dhū al-Ḥijja — ذو الحجّة — means “the one of pilgrimage” in Arabic, referring to the annual Muslim pilgrimage to Mecca, the Hajj.
Coptic calendar
The Coptic calendar, also called the Alexandrian calendar, is used by the Coptic Orthodox Church and still used in Egypt. This calendar is based on the ancient Egyptian calendar. To avoid the calendar creep of the latter, a reform of the ancient Egyptian calendar was introduced at the time of Ptolemy III (Decree of Canopus, in 238 BC) which consisted of the intercalation of a sixth epagomenal day every fourth year. However, this reform was opposed by the Egyptian priests, and the idea was not adopted until 25 BC, when the Roman Emperor Augustus formally reformed the calendar of Egypt, keeping it forever synchronized with the newly introduced Julian calendar. To distinguish it from the Ancient Egyptian calendar, which remained in use by some astronomers until medieval times, this reformed calendar is known as the Coptic calendar. Its years and months coincide with those of the Ethiopian calendar but have different numbers and names.
