Devil's advocate: people are hesitant to talk about specific times because days/years work differently depending on whether you're using standardized time or the unique time systems of the thousands of planets out there and it could be misinterpreted.
The Galactic Standard Calendar was established in S3 of Mando when they mentioned Taungsdays. Interplanetary commerce and travel would essentially require a standardized time and date system as well. The simplest answer is that Mr. Krabs just wrote a clunky speech.
I think that's a fair argument though I would expect a civilization that advanced and widespread to have adopted standard measures of time. Which I previously would have assumed a "year" to mean something like a full solar orbit of coruscant. There's no reason for there not to be multiple standards, though, but it would be nice if that's what they were going for they didn't just say "year".
