idusid
Idus is a Latin word that refers to the middle of a month in the ancient Roman calendar. The term "idus" is derived from the Latin verb "idire," which means "to go to." Each month in the Roman calendar had an "idus" day, which was the 15th day of the month for January, March, May, July, and September, and the 13th day for the other months. The ides were significant because they marked the midpoint of the month and were often used as a reference point for legal and financial transactions. The ides are also famous for the assassination of Julius Caesar on the Ides of March, 44 BC, which is a pivotal event in Roman history. The term "idus" is still used in modern Latin and other Romance languages to refer to the middle of a month.
