About Jumada al-Thani
Jumada al-Thani (جُمَادَىٰ ٱلثَّانِيَة) is the sixth month of the Hijri calendar. Its name means “The second of parched land.” The sixth month, also called Jumada al-Akhirah, completing the pair of Jumada months.
Like every Hijri month it has 29 or 30 days, determined in the Umm al-Qura calendar by the official tables and in the tabular calendar by a fixed arithmetic rule. Because the lunar month depends on the sighting of the new crescent, the exact first day can differ by a day from the calculated date.
