Turn a typed seed into the number the game really uses, turn any colour into the decimal the game stores, and move between ticks, seconds and the in-game clock.
Minecraft runs at 20 game ticks a second. A redstone tick is two game ticks, and a full day-night cycle is 24,000 ticks — twenty real minutes. The maths behind each box is in How the numbers are worked out.
Every formula this page uses, and the questions players ask most.
If what you type reads as a whole number inside the Java long range the game uses it exactly. Anything else goes through Java’s String.hashCode(), which returns a 32-bit number — so Minecraft becomes -1595926131.
Yes. String.hashCode() maps every possible phrase onto only 232 values, so collisions exist. Type the number instead if you want all 264 seeds.
24,000 game ticks, which is twenty real minutes. Day runs from tick 0 to 12,000, and the clock starts at 06:00.
Two game ticks, so a tenth of a second. A repeater on its first setting is one redstone tick; on its fourth it is four, which is 0.4 seconds.
Multiply out red × 65536 + green × 256 + blue. Deep green #4B8B2E is 4950830, which goes straight into dyed_color.
Tick 6000 is noon and tick 18000 is midnight. /time set 6000 puts the sun overhead.
