My script won't add one to an IntValue, how can I fix it?

I am trying to make a day/night script but also utilize values to change the day from Sunday, to Monday, and so on, but for some reason, the value won't change and I'm not receiving any errors.

local lighting = game:GetService("Lighting")
local replicatedStorage = game:GetService("ReplicatedStorage")
local event = replicatedStorage:findFirstChild("Time")

while wait(.9) do
 local hours = math.floor(lighting:GetMinutesAfterMidnight() / 60)
 local suffix = "AM"
 local minutes = lighting:GetMinutesAfterMidnight() - (hours * 60)
 if hours > 11 then
  hours = hours - 12
  suffix = "PM"
 end

 if hours == 0 then
  hours = 12
 end

 if minutes < 10 then
  minutes = "0" .. minutes
 end

 local text = hours .. ":" .. minutes .. " " .. suffix
 event:FireAllClients(text)
 lighting:SetMinutesAfterMidnight(lighting:GetMinutesAfterMidnight() + 1)
end

if game.Lighting.ClockTime == 0.00 or 00 or 0 then
    local value = game.Lighting.DotW
    for i = 1,1 do
    value.Value = value.Value + 1
    end
end
