Simple Day/Night Cycle Libgdx

Hello, this is my first post on here and sadly it has to be a question. I’ve been searching the site for an explanation on how this would be done but I have yet to find something that I could understand so I thought I would ask for a little assistance. I’m working on a side-scrolling game and I have been trying to find an effective way to implement a day/night cycle. I’m new at libgdx but I am using this project to work on it some more, so please try to go easy on my brain. If more information is needed I will be keeping an eye on this because I’m not totally sure what all I would need to post. Thanks anyone who could possibly help with this!
