Time of Day

Time of Day is a gameplay element in Dota 2 that operates alongside the game's clock. Certain mechanics behave differently depending on the time of day.

Day-Night-Cycle
Each day in Dota 2 is 8 minutes long, divided evenly between daytime and nighttime. Dawn starts at 0:00 by the horn Radiant Horn.mp3 (Radiant)/ Dire Horn.mp3 (Dire), the first night begins at 4:00, the second day starts at 8:00, and so on. Shifting from day to night and vice versa is signaled by an audio cue, with nighttime being announced with a wolf's howl Night.mp3, while daytime is announced with bird's tweet and rooster's crow Day.mp3.
