A countdown can start minutes, hours or days before a launch.
The length of the "final countdown" can vary based on the number of pre-launch steps that must be doneimmediatelybefore lift-off.
Space Shuttle Example:
- T-minus 31 sec: If all systems are OK, team issues the "Go" command. At this point launch control is handed off to the shuttle computers
- T-minus 16 sec: Water system starts spraying the launch pad, so it isn'tincinerated
- T-minus 6 sec: Start main engines, because it takes a moment for them to power up
- T-minus 0: The solid rocket boosters are ignited, then lift-off
-BUT- If you are shooting a model rocket in your backyard... feel free to start with any number you want.
