How do I make a timer?

I am trying to make a timer that counts down from 60. This script works perfectly but apparently it crowds up my script too much. Is there a shorter form of this timer?

local msg = Instance.new("Hint")
	msg.Parent = nil
	msg.Parent = game.Workspace
	msg.Text = "Intermission: 60"
	wait(1)
	msg.Text = "Intermission: 59"
	wait(1)
	msg.Text = "Intermission: 58"
	wait(1)
	msg.Text = "Intermission: 57"
	wait(1)
	msg.Text = "Intermission: 56"
	wait(1)
	msg.Text = "Intermission: 55"
	wait(1)
	msg.Text = "Intermission: 54"
	wait(1)
	msg.Text = "Intermission: 53"
	wait(1)
	msg.Text = "Intermission: 52"
	wait(1)
	msg.Text = "Intermission: 51"
	wait(1)
	msg.Text = "Intermission: 50"
	wait(1)
	msg.Text = "Intermission: 49"
	wait(1)
	msg.Text = "Intermission: 48"
	wait(1)
	msg.Text = "Intermission: 47"
	wait(1)
	msg.Text = "Intermission: 46"
	wait(1)
	msg.Text = "Intermission: 45"
	wait(1)
	msg.Text = "Intermission: 44"
	wait(1)
	msg.Text = "Intermission: 43"
	wait(1)
	msg.Text = "Intermission: 42"
	wait(1)
	msg.Text = "Intermission: 41"
	wait(1)
	msg.Text = "Intermission: 40"
	wait(1)
	msg.Text = "Intermission: 39"
	wait(1)
	msg.Text = "Intermission: 38"
	wait(1)
	msg.Text = "Intermission: 37"
	wait(1)
	msg.Text = "Intermission: 36"
	wait(1)
	msg.Text = "Intermission: 35"
	wait(1)
	msg.Text = "Intermission: 34"
	wait(1)
	msg.Text = "Intermission: 33"
	wait(1)
	msg.Text = "Intermission: 32"
	wait(1)
	msg.Text = "Intermission: 31"
	wait(1)
	msg.Text = "Intermission: 30"
	wait(1)
	msg.Text = "Intermission: 29"
	wait(1)
	msg.Text = "Intermission: 28"
	wait(1)
	msg.Text = "Intermission: 27"
	wait(1)
	msg.Text = "Intermission: 26"
	wait(1)
	msg.Text = "Intermission: 25"
	wait(1)
	msg.Text = "Intermission: 24"
	wait(1)
	msg.Text = "Intermission: 23"
	wait(1)
	msg.Text = "Intermission: 22"
	wait(1)
	msg.Text = "Intermission: 21"
	wait(1)
	msg.Text = "Intermission: 20"
	wait(1)
	msg.Text = "Intermission: 19"
	wait(1)
	msg.Text = "Intermission: 18"
	wait(1)
	msg.Text = "Intermission: 17"
	wait(1)
	msg.Text = "Intermission: 16"
	wait(1)
	msg.Text = "Intermission: 15"
	wait(1)
	msg.Text = "Intermission: 14"
	wait(1)
	msg.Text = "Intermission: 13"
	wait(1)
	msg.Text = "Intermission: 12"
	wait(1)
	msg.Text = "Intermission: 11"
	wait(1)
	msg.Text = "Intermission: 10"
	wait(1)
	msg.Text = "Intermission: 9"
	wait(1)
	msg.Text = "Intermission: 8"
	wait(1)
	msg.Text = "Intermission: 7"
	wait(1)
	msg.Text = "Intermission: 6"
	wait(1)
	msg.Text = "Intermission: 5"
	wait(1)
	msg.Text = "Intermission: 4"
	wait(1)
	msg.Text = "Intermission: 3"
	wait(1)
	msg.Text = "Intermission: 2"
	wait(1)
	msg.Text = "Intermission: 1"
	wait(1)
	msg.Text = "Intermission: 0"
	wait(1)

Your script is perfect! You only lack efficiency. Would you rather have a 125 line script or a 6 line script. Try out this script:

local msg = Instance.new("Hint")
msg.Parent = game.Workspace
for i = 0, 60 do
	msg.Text = "Intermission: ".. 60 - i
    	wait(1)
end

Well, your script should work perfectly fine. But efficiency-wise it suffers. To fix up your script then what you can do is use a For loop to go through all the numbers, this way then each time the for loop iterates, we can set the text to the current number(:

local msg = Instance.new("Hint",game.Workspace)

for i = 60,0,-1 do --Start, end, increment
	msg.Text = "Intermission: "..tostring(i) --Use tostring so you can concatenate the 'i' value.
end
