# How Long Is A Redstone Night In Minecraft?

I am currently creating a debuff system that gives you slowness during the night if you don't use a bed. I am using a daylight sensor and was wondering how long the effect should last. I thought just a full night would be fine but now I need to know (in real time) how long a night is (Or more specifically how long a daylight sensor doesn't send out a redstone signal for). Thanks!

• While somewhat tangential to the linked question, night length is indeed covered. – John the Green Jan 25 '14 at 23:00
• @NovaSword After rereading it, I think the question is not a duplicate because the asker wants to know how long night is from the perspective of a redstone circuit, rather than the player's/skybox, which is what I was answering in that other question. The difference is that it's not clear how long the period is from transition to transition; I suppose it's somewhere between 7 minutes and 10, but I don't know just how long it is. – badp Jan 25 '14 at 23:08
• (Also, I'm afraid that answer might depend on torches or the weather if the circuit is triggered by light levels.) – badp Jan 25 '14 at 23:12
• @badp If he is asking about it from the perspective of a redstone circuit, then I agree it's not a duplicate. – NovaSword Jan 25 '14 at 23:18

From the Minecraft Wiki:

### Daytime

Daytime is the longest section of the cycle, lasting 10 minutes in PC and 6 minutes in Pocket Edition.

### Sunset/dusk

Lasts 1 1⁄2 minutes in PC and 9⁄10 of a minute in Pocket Edition.

### Nighttime

Lasts 7 minutes in PC and 4 1⁄5 minutes in Pocket Edition.

### Sunrise/dawn

Lasts 1 1⁄2 minutes in PC and 9⁄10 of a minute in Pocket Edition.

A light sensor should output 15 for ten minutes, go down to zero over 1.5 minutes, stay at zero for seven minutes, and go back up to 15 over 1.5 minutes.

A night in Minecraft is approximately 7 minutes in real life.
