Arabic names of Gregorian months

These names are used primarily in Iraq, Syria, Jordan, Lebanon and Palestine. They are inherited from Classical Arabic and ultimately derived from the Syriac names of the Assyrian calendar. These names are cognate with some of the names of the Babylonian and Hebrew calendars. Nine of these names were used in the Ottoman Turkish calendar, of which five remain in use in the modern Turkish calendar.

The names of the Gregorian months in Egypt, Sudan and the Arab states of the Persian Gulf are based on the old Latin names.

The names of months used in the Great Socialist People's Libyan Arab Jamahiriya (1977–2011) were derived from various sources, and were assembled after Muammar Gaddafi's seizure of power in 1969 and abolished in 2011 after the 17 February Revolution. The decision of changing calendar names was adopted in June 1986.[2] Although the Libyan calendar followed the same sequence of renamed Gregorian months, it counted the years from the death of the prophet Muhammad.[3] This reckoning was therefore ten years behind the Solar Hijri calendar used in Iran and Afghanistan.

The names of the Gregorian months in Algeria and Tunisia are based on the French names of the months, reflecting France's long colonisation of these countries (1830–1962 in Algeria; 1881–1956 in Tunisia).

As Morocco was long part of the Roman Empire, the long-standing agricultural Berber calendar of the country preserves the Julian calendar and (in modified form) the names of its months. There are regional variations of the Berber calendar, since some communities did not recognise the Julian 29 February in century years where the Gregorian calendar had no equivalent date. When Morocco adopted the Gregorian calendar for civil purposes, the names of the months were taken from this local tradition.
