Jumada al-Awwal (Arabic: جُمَادَىٰ ٱلْأَوَّل, romanized: Jumādā al-ʾAwwal, lit. 'The initial Jumada'), also known as Jumada al-Ula (Arabic: جُمَادَىٰ ٱلْأُولَىٰ, romanized: Jumādā al-ʾŪlā, lit. 'The first Jumada'), or Jumada I, is the fifth month of the Islamic calendar. Jumada al-Awwal spans 29 or 30 days. The origin of the month's name is theorized by some as coming from the word jamād (Arabic: جماد), meaning "arid, dry, or cold", denoting the dry and parched land and hence the dry months of the pre-Islamic Arabian calendar. Jumādā (Arabic: جُمَادَىٰ) may also be related to a verb meaning "to freeze", and another account relates that water would freeze during this time of year. The secondary name Jumādā al-Ūlā may possibly mean "to take charge with, commend, entrust, commit or care during the arid or cold month". However, this explanation is rejected by some as Jumada al-Awwal is a lunar month that does not coincide with seasons as solar months do.
In Turkish, the name of the month is cemâziyelevvel (Ottoman Turkish: جماذیالاول); it was abbreviated as جا ca in Ottoman Turkish.
Timing
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 tropical year, Jumada al-Awwal migrates backwards throughout the seasons in a cycle of about 33 solar years. The estimated start and end dates for Jumada al-Awwal are as follows (based on the Umm al-Qura calendar of Saudi Arabia:)
