Jumada al-Thani (Arabic: جُمَادَىٰ ٱلثَّانِي| Jumādā ath-Thānī|lit=The second Jumada), also known as Jumada al-Akhirah (Arabic: جُمَادَىٰ ٱلْآخِرَة|link=no|Jumādā al-ʾĀkhirah|lit=The final Jumada), Jumada al-Akhir (Arabic: جُمَادَىٰ ٱلْآخِر|link=no|Jumādā al-ʾĀkhir), or Jumada II, is the sixth month of the Islamic calendar. The word Jumda (Arabic: جمد), from which the name of the month is derived, is used to denote dry, parched land, a land devoid of rain. Jumādā (Arabic: جُمَادَىٰ) 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.
In Ottoman Turkish, the month was called Jèmāzìyyu-'l-ākhir,[1] or G̃emazi-yèl-Aher.[2] The month's Turkish abbreviation was jìm,[1] and its Latin abbreviation was Djem. II.[3] This is also spelled Cümadelahir[4] or Cümâd-el-âhire. The modern Turkish spellings are Cemaziyelahir and Cemaziyelsani.
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 al-Thani migrates throughout the seasons. The estimated start and end dates for Jumada al-Thani are as follows (based on the Umm al-Qura calendar of Saudi Arabia[5]):
