@Topdawg2881 that's where I was going with my example. There is still the delay(500) that I left in from his code, but that's a short delay.

if it is an emergency button should be connected directly to relay (connected by hardware). And not using code,because if arduino it's freezed it will not respond and you cant stop it

Well i need to finish this Project until the end of this month so o dont have time to learn, im learning arduino but slower, i dont want a magic code just nisto way of programing the switch buttons to change the time, or where tofind

@Bruno-Cunha it is not a variable, and using - 5 would be the same, but using 5 makes it harder to understand and maintain the code. See https://refactoring.com/catalog/replaceMagicNumberWithSymbolicConstant.html for more info on why I prefer using define.
