When tracking a launch schedule, how close to liftoff is the Go/No-Go status typically finalized?

This critical information is often released just a few hours prior to the targeted liftoff time.

Launch schedules are inherently volatile, subject to constant shifts caused by weather patterns, ongoing technical checks, and mission objectives. Therefore, absolute final confirmation of launch readiness is withheld until the last possible moment to allow for dynamic adjustments. The official 'Go/No-Go' confirmation, which verifies that all prerequisite conditions—technical, environmental, and procedural—have been met, is usually communicated to the public and stakeholders only a very short time before the intended liftoff window opens, often just a few hours before the targeted time. This late confirmation necessitates that viewers always verify this status immediately before departing for physical viewing locations.
