難易度
English uses time adverbs and prepositions such as at, on, in, for, and since to locate events in time.
I arrived at six yesterday.
at six yesterday = time point/span
よくあるつまずき
Learners often mix up at/on/in, for/since, and word order of time expressions.
Same block, different coding
Both languages use this block strongly, but they signal it differently. Focus on form changes, not only meaning.
