It sounds like you want to know how to make something open after hours later in Roblox, like a door or gate that unlocks after a timer. A simple way is to set a wait time, then change the part’s visibility and collision so players can pass through it.

Simple Roblox door script

Put a Script inside the door part:

lua

local door = script.Parent

task.wait(3600) -- 1 hour

door.Transparency = 1
door.CanCollide = false

If you want it to close again later , you can add another wait and switch the values back. Roblox DevForum examples use Transparency and CanCollide for this exact behavior.

If you want a repeating timer

lua

local door = script.Parent

while true do
	task.wait(3600) -- closed for 1 hour
	door.Transparency = 1
	door.CanCollide = false

	task.wait(10) -- open for 10 seconds
	door.Transparency = 0
	door.CanCollide = true
end

That version makes the door open every hour, stay open for 10 seconds, then close again.

If you meant the Roblox game

There are walkthrough videos and a wiki page for After Hours on Roblox, which suggest it is a horror game about surviving overnight in a store. If you meant how to open a specific door or area in that game, the exact solution depends on the chapter or room.

Short version

  • Use task.wait(time) for the delay.
  • Set Transparency = 1 to hide the door.
  • Set CanCollide = false so players can walk through it.
  • Reverse those values to close it again.

If you want, I can turn this into a version for a ProximityPrompt , a button , or a key door.
