Jumada Al Thani 2022 starts from 24 December to 22 January 2023. The origin of the name is theorized by some as from the word jamād ( جماد) meaning "arid, dry, or rainless" - denoting the dry and parched land, hence the dry months. Jumādā (جُمَادَىٰ) may also be related to a verb meaning "to freeze" and another account relates that water would freeze during this time of year.
