Automatic Calendar

We have an event with no definite date scheduled, but a set of defined
relationships (such as, event A will happen 30 days after event B; event C
must happen no later than 15 days after event D; etc.). I'd like to set up a
calendar so that if we input a couple of dates, it will automatically fill in
the other dates based on the relationships. Are there Excel functions that
can do this?

I just asked this question, and after another few min of messing with it I figured out how... Are you still seeking an answer?
