A free mod for Fallout 4, by m8r98a4f2.

FallUI – Sleep and Wait is an application that allows you to customize the gameplay of your game, in this case, the game Fallout 4. In this application, you will find a complete overhaul of the sleep and waiting menu, with the possibility to customize the time of the day, the number of hours, and even the type of sleep you want to have.

This mod features configurable target time buttons, so you no longer have to calculate. You can also change the format of the time and date. With this, you will also get access to a daytime graph showing the current time marker, target time arrow, and daytime lightness. You can also configure the start day of the week.

This is simple and easy to install. You can use any mod manager.
