Alignment Date

Ok so I want to test a Duna Lander, and I'm waiting for my kerbin and duna to line up enough to fire an intercept. So what I'm wondering if anyone has found the dates that the planets line up enough to intercept.

There are 2 excellent tools available to give (also) dates for interplanetary transfers (or, launch windows):

- Alexmun's Launch Window Planner (web app);

- Arrowstar's KSP Trajectory Optimization Tool (matlab runtime required).

Also, the problem can be solved by MrEnigma03 Protractor (KSP plugin), though it is based on angles/time differences rather than on dates.
