Jumada II (Arabic: جُمَادَى ٱلثَّانِيَة, romanized: Jumādā th-Thāniya,[a] lit.'Jumada the Second', more commonly called جُمَادَى ٱلْآخِرَة, Jumādā l-ʾĀkhira,[b] lit.'Jumada the Last')[c] is the sixth month of the Islamic calendar. The word jamād (جماد), from which the name of the month is derived, is used to denote dry, parched land, a land devoid of rain. Jumādā (جمادى) may also be related to a verb meaning 'to freeze', and another account relates that water would freeze in pre-Islamic Arabia during this time of year.
The Islamic calendar is a purely lunar calendar, and months begin when the first crescent of a new moon is sighted. Since the Islamic lunar year is 11 to 12 days shorter than the solar year, Jumada II migrates throughout the seasons. The estimated start and end dates for Jumada II are as follows (based on the Umm al-Qura calendar of Saudi Arabia[1]):
