I am a little more than a year away from my funding running out (not taking into account any Covid-related extensions which may or may not be granted and thus can't be relied on). Hence, I would consider this date the target end date for my PhD after which I would like to move on from my current institution.

I have identified a handful of potential advisors for postdocs (in Europe, mostly). How early should/can I get in touch with them? Obviously, I would like to do it as early as possible (as there is a chance that means I can plan better). However, I don't want to do it too early to the point where it would seem weird / be pointless.

I am in science doing my PhD in Europe, should that be of help.
