Unless I am mistaken a  formula for computing the length of the year is in fact
given in book 6
if there isn't a formula there The following should work:
        (r^3/2)/(m^1/2)
where r is the star-planet radius in AU and m is the stars mass in solar
(earth sun) masses. The result is given in earth years.
the length of day is highly variable and there isn't really any way to generate
it using any formula one good way might be to roll 7 dice and add them together.
This will generate results that fit roughly into an acceptable range (7 is a
little low, but is sufficiently rare) and will center around 24 hours which
seems to be a number conducive to human life
As for the seasons this is a diffucult question, as a season is really a change
in the climate. And as the climate at a given point on the surface of a given
planet is a function of a lot of variables I can't think of any way of
predicting the season without working it out on a case by case basis.
The equinoxes and solstices will however follow the same progression as they do
here being separated by 1/4 of the year.
I hope this was of some help.
