Why is rounding still giving decimal numbers?

Not much to say really but just that when make my server age counter, it is not rounding the numbers, despite me using math.ceil(Number + Closest). anyway I need some hepl with this script!

local TempNumber

game.ServerStorage.ServerAge.Changed:connect(function()
	if game.ServerStorage.ServerAge.Value < 60 then
		script.Parent.Text = game.ServerStorage.ServerAge.Value .. " Seconds"
	else
		if game.ServerStorage.ServerAge.Value < 3600 then
			TempNumber = game.ServerStorage.ServerAge.Value / 60
			script.Parent.Text = math.ceil(TempNumber + 60) .. " Minutes"
		else
			if game.ServerStorage.ServerAge.Value < 86400 then
				TempNumber = game.ServerStorage.ServerAge.Value / 3600
				script.Parent.Text = math.ceil(TempNumber + 3600) .. " Hours"
			else
				if game.ServerStorage.ServerAge.Value < 604800 then
					TempNumber = game.ServerStorage.ServerAge.Value / 86400
					script.Parent.Text = math.ceil(TempNumber + 86400) .. " Days"
				else
					if game.ServerStorage.ServerAge.Value < 2628000 then
						TempNumber = game.ServerStorage.ServerAge.Value / 604800
						script.Parent.Text = math.ceil(TempNumber + 604800) .. " Weeks"
					else
						TempNumber = game.ServerStorage.ServerAge.Value / 2628000
						script.Parent.Text = math.ceil(TempNumber + 2628000) .. " Months"
					end
				end
			end
		end
	end
end)

Thanks!
