So, I'm trying to figure out a world's cycle (length of a year, day, etc.). The planet, Vixeruka, is about 3 times larger than Earth is, making it a super-Earth, and it's the second planet from its sun, a K4V class star, so it's a main sequence star. The planet has rings around it and two moons. It's located in the habitable zone as well. Pretty much dab smack in the middle of the Goldilocks Zone to be specific.

So my best guess is that it takes the planet to go around its sun in about say 14 months, and that a day is about 28 hours long, and there's about 8 days in a week. But I'm not sure if I've got my math right.

My questions are how do I properly figure out the the period of rotation of the planet and the period of revolution, and what would those statistics be?
