Schedule Timer - Possibly working overboard on doing this?

I'm trying to generate a bell system relying on a table.. I feel like there's an easier method of checking what time its on, and using it to check what period its on. So far, here is my results.

PSchedules={
    {"TESTBLOCK",{
    --  name            time start  time end
        {"Period 1",    10,41,      10,43},
        {"Period 2",    10,45,      10,46},
        {"Period 3",    10,47,      10,49},
        {"Period 4",    10,50,      10,51}
    }}
}
require game.ServerScriptStorage.GetTime; --returns a function that gives back my current time in this format (return hour,min,sec,amORpm)
function StartBell(schedu)
    local bellloop=true
    local schn=tonumber(schedu)
    if schn~=nil then
        local hours,mins,secs,pm=GetTime()
        local checkloop=1
        local isonperiod=false
        for a=1,#PSchedules[schn][2] do
            print(hours,PSchedules[schn][2][a][2])
            if hours>=PSchedules[schn][2][a][2] then 
                if mins>=PSchedules[schn][2][a][3] then
                    print("passd "..schn,a)
                    checkloop=a
                end 
            end 
        end 
        if hours <= PSchedules[schn][2][checkloop][4] then
            if mins < PSchedules[schn][2][checkloop][5] then
                isonperiod=true
            end

                            isonperiod=true
                        end
                    end 
                end 
            end

                end

                    print("The bell could NOT find the next loop and died..")
                else
                    if PSchedules[schn][2][checkloop][2]==hours then
                        if PSchedules[schn][2][checkloop][3]<mins then

                        end 
                        if PSchedules[schn][2][checkloop][5] > mins then
                            remainmins=remainmins+PSchedules[schn][2][checkloop][3]-mins
                        end
                    end
                end

            print("----------------------------------")

        until bellloop==false
    end
    print("TheBellDied..")
    bellloop=false
end 
StartBell(1)

Am I going overboard on how to check for this information, or is their an easier way?
