Journeys skipping the first day in Rome (4)

I believe the answer is:

ides

I'm a little stuck... Click here to teach me more about this clue!

'day in rome' is the definition.
(Roman calendar term, as in the Ides of March)

I don't understand the rest of the clue.

Can you help me to learn more?

(Other definitions for ides that I've seen before include "March 15; dies (anag.)" , "Fatal March date or Julius Caesar" , "For Romans, a day" , "Caesar's bad day in March" , "Day in Roman months" .)

I've seen this clue in The Times and The Sunday Times.
