Day of the week GUI in roblox stays at the same day and does not change?

I have tried this so far and it works, but it stays on the same day of the week and does not change which is weird because there are no errors in the output.

##Script:

local daysOfTheWeek = {
    "Sunday",
    "Monday",
    "Tuesday",
    "Wednesday",
    "Thursday",
    "Friday",
    "Saturday"
}

for i=1, #daysOfTheWeek do
    for _, plr in pairs(game.Players:GetPlayers()) do
        local plrGui = plr:WaitForChild("PlayerGui")
        local serverWeekGui = plrGui:WaitForChild("ServerWeekGui")
        serverWeekGui.TextLabel.Text = daysOfTheWeek[i]
    end
    while not game.Lighting.ClockTime == 0 do
        wait(1)
    end
end

What I want is for when the clock time changes to 0 for the day to change to the next day. Like say it's Monday, I want the day to change to Tuesday.

##Problem: The problem you're encountering is that you're trying to Wait for the child of "ServerWeekGui". This GUI is a screen GUI, and would not work, because you cannot change the ScreenGui.

##Solution

To resolve this, you'd simply have to index the hierarchy of the screen GUI, the (Textabel), and that would fix your error, this would index the text label, so it would actually run!

##Fixed Script:

DAY/Night cycle script: (The below script works):

local daysOfTheWeek = {
	"Sunday",
	"Monday",
	"Tuesday",
	"Wednesday",
	"Thursday",
	"Friday",
	"Saturday"
}

for z=1, #daysOfTheWeek do

	for _, plr in pairs(game.Players:GetPlayers()) do
		local plrGui = plr:WaitForChild("PlayerGui")

		local serverWeekGui = plrGui:WaitForChild("ScreenGui").TextLabel1 -- change "TextLabel1" to your textlabel name
		for i = 1, 23 do
			wait(5) -- change how fast the clocktime arises
			game.Lighting.ClockTime = i -- changes the clock time to the index
			if game.Lighting.ClockTime == i then
				serverWeekGui.Text = daysOfTheWeek[z]   -- changes the text to the days of the week
			end
		 end
	  end
  end
