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!
