also rested bonus lasts 23 minutes if done right. a day in valheim lasts 21 minutes. a night is 9 minutes. this is without seasonal bonus time items. otherwise its 25 minutes.

thats long enough i would say.

That assume you want to play with a pocket portal.

You only get around 11 minutes if you sleep in a rock, but, fortunately you can go to bed very early in this game. :-)
