Ideal sun type and corresponding effects for a terrestrial planet with 256 days in a year?

The planet has 256 days in a year, split up into eight months, each with 32 days.

My planet is a bit smaller than Earth: Think, enough space for the continents of Earth's western hemisphere and the Pacific Ocean, only the continents are split up a bit and there are islands scattered across the other side of the planet, where there would otherwise be only water. I'm hoping to avoid any extreme world-wide climate effects on account of star type and orbital period, because I'd like for the climates across the world to be fairly Earth-like in variation.

What star type would be ideal for this planet based on the length of its year that would also give it a climate comparable to Earth's? Could the hours in a day be the same (For instance, would midnight still be the twelfth hour?) Would there be any slight or glaring effect on climate or atmosphere? And what would this star look like in the sky? Would its journey from one horizon to another be different?

Ideally, I'd like for the differences to be slight, though I have no qualms with describing a star that is different from ours or a difference in daily hours. An additional moon or a moon that is clearly different from ours is fine if it helps accomplish what I'm looking for.

The inhabitants of this world are not space faring or remotely as technologically advanced we are; they are fairly primitive. My concern was the odd year length, which is pivotal to the story, and the idea that the planet's rotation and star could not realistically be exact to Earth's, which is more than fine, I'm just unsure how to figure this out on my own.

I would've posted this on the astronomy stack, but was led to believe by a question on meta that they disapprove of questions about imaginary planets there. However, if this question is more appropriate for that site, please let me know and I'll remove it from here. Also, if there is any additional information that I should add to make my question easier to answer, just say the word and I'll do my best. Thanks in advance.
