Making a script that prints text on certain time doesnt work?

So I am trying to make script, that prints text on set time. I want it to print midnight on 00:00:00 of clock time and noon on 12:00:00. But for some reason, unknown for me, its not doing anything. Any idea what mistake am I doing.

function DayNightDoorCycle()
	while true do
		if game.Lighting:GetMinutesAfterMidnight() == 0 then
			print ("midnight")
		end
		
		if game.Lighting:GetMinutesAfterMidnight() == 720 then
			print ("noon")
		end
	end
end

local function DayNightDoorCycle()
    while true do
        if math.floor(game.Lighting:GetMinutesAfterMidnight()) == 0 then
            print ("midnight")
        elseif math.floor(game.Lighting:GetMinutesAfterMidnight()) == 720 then
            print ("noon")
		wait() -- it stopped due to server exhuast execution
        end
    end
end

Also, i reccomend using a function to check, like a getpropertychangedsignal or changed, as indefinite loops are't healthy. Also, you shopuld put a inf loop into a function, otherwise it will keep looping and the rest of the function lines won't run.

also, the values might constantly be changing in values, so i added math.floor()
