Jumada al-Thani (Arabic: جُمَادَىٰ ٱلثَّانِي, romanized: Jumādā ath-Thānī, lit. 'The second Jumada'), also known as Jumada al-Akhirah (Arabic: جُمَادَىٰ ٱلْآخِرَة, romanized: Jumādā al-ʾĀkhirah, lit. 'The final Jumada'), Jumada al-Akhir (Arabic: جُمَادَىٰ ٱلْآخِر, romanized: 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.[citation needed]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.
The Islamic calendar is a purely lunar calendar, and months begin when the first crescent of a new moon is sighted.

The estimated start and end dates for Jumada al-Thani are as follows (based on the Umm al-Qura calendar of Saudi Arabia[1]):
