I need help deciding when to head back from Duna

[Guest]

Here is the current issue

My issue is when and how to get back there. I set it up based on what websites have told me but I do have another save after undocking the lander that was 9 days after my arrival so I can revert 

But still, I don't know how and when. Please tell me before this Thursday!  Or else those poor kerbals will have to die.

Here's a way to figure that out.

The answer is to launch when Duna is about 75 degrees ahead of Kerbin. 

Oh, and thread moved to Gameplay Questions, since it is seeking help rather than offering it.

Okay whoops about the Thread  still getting used to it

I've used the website but the main issue is where would Kerbin would be when I do it.

[Vanamonde]

No problem.   And 75 degrees behind Duna.

If Duna is at the 6 o'clock position with the view centered on the sun, Kerbin should be at the 8:30 position for a minimum-energy transfer, about your current situation I think.  Launch to leave Duna's SoI directly retrograde.  If it shows you arriving too soon, angle your departure to be a bit away from the sun, and you'll need to add a bit of delta-v to get the periapsis back down.
