When you want to use a past participle to define a noun, should you place it before or after the noun? e.g. "the agreed date" or "the date agreed"?
In that case, either. I don't know if there's a more general rule - I can't find one in Swan, but stay tuned! (If you register - quick and free - you can get e-mail notification when people respond to particular threads.)
If you want to add some defining details to the participle, it goes after:
'Please have this report ready on the date agreed at our last meeting.'
But these two are both acceptable:
'Please have this report ready on the date agreed.'
'Please have this report ready on the agreed date.'
