As a suffix, -idus denotes state of being, translated roughly as "having the nature of". Example: the Latin word herbidus (grassy, or plant-like), from the word herba(plant) and the suffix idus (having the nature of).
As a word on its own, Idus is Latin for "Ides". The Romans specified dates not by numbering all the days of the month, but by counting backwards from certain fixed days:

Nonae "Nones": the 7th of March, May, July and October, and the 5th of other months
Idus "Ides": the 15th of March, May, July and October, and the 13th of other months
