Not sure about naming fantasy things

I'm doing a fantasy world, a new planet and all.
How logical must it be? If the planet is larger than Earth, does it mean it has to have different seasons? More days in a year than Earth? How many hours a day? Or is there an excuse if it's magical world?
And when naming buildings or books, do they have to be some super fantasy names or should I not make it too difficult.
For example a book about dragons: Dragonic Pyromancy: A breath of Fire and Flame
Or simple: Book of Dragons
