etymonline
July
seventh month, c. 1050, Iulius, from Anglo-French julie, Old French Juil, Jule (Modern French uses a diminutive, Juillet) and directly from Latin Iulius "fifth month of the Roman calendar" (which began its year in March), renamed after his death and deification in honor of Gaius Julius Caesar, who was born in this month. In republican Rome it had been Quintilis, literally "fifth." Compare August. Accented on the first syllable in English until 18c.; "the modern Eng. pronunciation is abnormal and unexplained" [OED]. Replaced Old English liða se æfterra "later mildness," from liðe "mild."
