Darkness icon

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.

As soon as a match starts (after the heroes from both factions have been shown), the clock starts at one of the following values, depending on the game mode:

  • -85 in a regular match.
  • -80 in a Play vs Bots match.
  • -70 in a Turbo match.
    • However, New_Player_Mode starts at -85, despite using the Turbo ruleset. Item availability isn't adjusted here, meaning that because of the extra time spent in the preparation phase, items such as Aghanim's Shard icon Aghanim's Shard will become available in the shop 15 seconds "earlier".
  • 0 in the Demo Hero mode.

Day-Night Cycle[]

DayNight

The Day/Night indicator in the default HUD.

Each day in Dota 2 is 6.6666666666667 minutes long, divided evenly between daytime and nighttime. Each match starts out at nighttime during the preparation phase pre-horn. Once the ▶️▶️ horn sounds (Radiant/Dire) and the game time reaches 0:00, the first dawn starts. The first night begins at 3.3333333333333:00, the second day starts at 6.6666666666667:00, 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 ▶️, while daytime is announced with a bird's tweet and a rooster's crow ▶️. Some custom maps may have their own version of these audio cues.

At night, the map is darker and most units experience reduced vision, as detailed below. Additionally, some heroes have their abilities modified according to the time of day, with the most notable example being Night Stalker minimap icon Night Stalker.

Alt+Keyboard White Mouse Left Left Click the clock prints the time in allied chat, and also prints whether Bounty Rune minimap icon Bounty Rune and/or Powerup runes are spawning soon.

Game Clock Modifying Abilities[]

The following abilities can change the current time of day, but these abilities do not pause the day-night cycle.

Game Clock Modifying Abilities According to Priority
  • Supernova icon
    Duration: 6
    Turns night into day for its duration.
  • Eclipse icon
    Duration: 2.4/4.2/6
    Turns day into night for 10 seconds. Eclipse has a lower priority than the daytime caused by Supernova icon Supernova.
  • Dark Ascension icon
    Duration: 30
    Turns day into night for its duration. Dark Ascension has a lower priority than the daytime caused by Supernova icon Supernova.

Affected Abilities[]

Neutral Creeps[]

Main Article: Neutral Creeps

During Nighttime nighttime, all neutral creeps, except for Roshan icon Roshan, are sleeping. This means during the night, their aggro range is reduced to 0, so they do not attack enemies who get too close to them. To draw their aggro, they must be damaged, or be targeted by a single-targeted ability. Besides not automatically drawing aggro, the creeps behave the same as during the Daytime daytime. When returning to their camp after de-aggroing, they go back to sleep as soon as they reach their original spot.

Sleeping creeps are indicated by floating Zs above the creeps.

Vision[]

Main Article: Vision

All heroes have a Daytime daytime and Nighttime nighttime vision range of 2000 and 500 respectively, except for the following:

Unit Day Night
Bane minimap icon 1800 1200
Slark minimap icon 1800 1800

Talents[]

The following heroes have a Talent talent that grants them bonus vision.

Bonus Level 10 Level 15 Level 20 Level 25
