Morphology
The verb 'look' (to appear) plus the phrase 'a day over [age]' is partly compositional — literally suggesting being a day older than the stated age — so a learner who knows the words can form a basic sense. However, the conventionalized, pragmatic use (especially in the negative form 'doesn't look a day over X' meaning 'appears no older than X / very youthful') is idiomatic and not fully predictable from the parts, making the expression only partly transparent to learners.
Etymology
Look a day over comes from the simple idea that even 'a day' more in age would show on your face. So saying someone looks a day over thirty means they 'are no older than thirty' and is a way to say they look young.
