Would it be the best time if I asked my supervisors for references (for future jobs) during the final year (early month) of the PhD programme?

My rationale is that they would be busy (most of the time) so I might just ask them as soon as possible; do you think it's reasonable?

Hi Dan
I think its best to ask them when you are nearing the end. I have found that discussing job options with my supervisor has been really helpful--but this is my experience, other people may have different advice on this. I feel that it all comes down to having a good relationship with the people who will be our references.
