I have a quick question, and I'd be grateful if anyone would help me out.
I know that 'time at which' should be in the ablative, but I'm not quite sure how to apply this to specific dates. For example, how would I say something like 'on (Ante Diem Decimum Kalendas Octobres) I went to Asia.'
Would I have to put some of the date into the Ablative, and if so, which bits? Or ...
