Do you want it to be updated while the user is editing or once the record is saved?
1) When the record is saved:
1.a) Use a workflow rule and a field update action to achieve that.
1.b) Use a trigger (cons: need testing and should be bulk friendly)
1.c) Use apex-code before saving to do that. (cons: need testing and should be bulk-friendly)
2) When the record is being edited
2.a) Use Javascript (pros: fast, cons: need to know a little bit of JavaScript)
2.b) Use apex:actionsupport, onchange event and rerender in your visualforce. (cons: it is a little bit slower, as it is executed server-side).
Hope this helps. I might have forgotten more options, but at least with this bit, you can make a decision.
This can be done using the apex:actionsupport onblur event/onchange event on the manufature date field.
