Day Cycle - Stardew Valley Wiki

The day cycle is a period of 20 hours in-game from 6am to 2am in which the player (farmer) is able to work and perform other activities around the Valley. The player will always wake up at the same time every day, but they are able to choose to go to bed whenever they like, which in turn ends the day.
