How to convert seconds to days, hours, minutes and seconds?

So im making a countdown to a day and i want to convert my seconds to days, hours, minutes and seconds.

My code

local TARGET_TIME = 1591525920

while wait(1) do
	if os.time() >= TARGET_TIME then
		start()
		break
	end
	
    local seconds = TARGET_TIME - os.time()
 -- here is where i want to convert the seconds variable into days, hours, mins and secs
end
