How do I make sounds play at a specific time?

How do I make sounds play at a specific time? I am trying to make this phone play these sounds when it turns midnight. I'm not getting any errors, but the sounds aren't playing. Like, at all. And I am also trying to get them to play at different days of the week, but I don't know if it's the day tracker on here that's messing everything up or not.

local Night = 1

while true do
	wait(0.5)
	if game.Lighting.ClockTime == 0 then
		if Night == 1 then
			script.Parent.Night1:play()
			print(Night)
			Night + 1
		end
		if Night == 2 then
			script.Parent.Night2:play()
			print(Night)
			Night + 1
		end
		if Night == 3 then
			script.Parent.Night3:play()
			print(Night)
			Night + 1
		end
		if Night == 4 then
			script.Parent.Night4:play()
			print(Night)
			Night + 1
		end
		if Night == 5 then
			script.Parent.Night5:play()
			print(Night)
			Night + 1
		end
		if Night == 6 then
			print(Night)
			Night + 1
		end
		if Night == 7 then
			print(Night)
			Night - 6
		end
	else
		wait()
	end
end

And here is the code for the script that changes the time.

local dayLength = 24 --How many minutes a full day(24 hours) will last

local cycleTime = dayLength*60
local minutesInADay = 24*60

local lighting = game:GetService("Lighting")

local startTime = tick() - (lighting:GetMinutesAfterMidnight()/ minutesInADay)*cycleTime
local endTime = startTime + cycleTime

local timeRatio = minutesInADay / cycleTime

if dayLength == 0 then
	dayLength = 1
end

repeat
	local currentTime = tick()
	
	if currentTime > endTime then
		startTime = endTime
		endTime = startTime + cycleTime
	end
	
	lighting:SetMinutesAfterMidnight((currentTime - startTime)*timeRatio)
	wait(1/15)
until false

How are you changing the time in your game?

Swap out the while loop with a :GetPropertyChangedSignal("ClockTime"). What I see here is that all 5 sounds play all at once if that's what you want otherwise, you can add something like this

script.Parent.Night1.Ended:Wait()

Always avoid using wait(n), the best solution is using :Wait() with events.

When changing the time or doing something like this, always do it on the Server via Script.

local Lighting = game:GetService("Lighting")

local Night = 1

Lighting:GetPropertyChangedSignal("ClockTime"):Connect(function()
    if Lighting.ClockTime == 0 then
        if Night == 1 then
            script.Parent.Night1:play()
            script.Parent.Night1.Ended:Wait()
            print(Night)
            Night + 1
        end
        if Night == 2 then
            script.Parent.Night2:play()
            script.Parent.Night2.Ended:Wait()
            print(Night)
            Night + 1
        end
        if Night == 3 then
            script.Parent.Night3:play()
            script.Parent.Night3.Ended:Wait()
            print(Night)
            Night + 1
        end
        if Night == 4 then
            script.Parent.Night4:play()
            script.Parent.Night4.Ended:Wait()
            print(Night)
            Night + 1
        end
        if Night == 5 then
            script.Parent.Night5:play()
            script.Parent.Night5.Ended:Wait()
            print(Night)
            Night + 1
        end
        if Night == 6 then
            print(Night)
            Night + 1
        end
        if Night == 7 then
            print(Night)
            Night - 6
        end
    end
end
