Minecraft Redstone Tick Calculator

Minecraft runs at 20 ticks a second and a full day is 24000 of them — 20 real minutes. Redstone adds a second unit on top: repeaters are set in redstone ticks, each worth two game ticks. This converts between all of them and works out the delay of a repeater chain, so you can time a clock without counting in your head.

20 game ticks a second, 24000 to a full day — 20 real minutes. A repeater’s setting is in redstone ticks, and one redstone tick is two game ticks, so a 4-setting repeater delays 8.
