Arduino Mega2560 Stops working

Hi, i am a beginner. I have a problem, arduino sometimes stops working (he just gets stuck) after the "If" function, (part of the code is marked in yellow).
Help me, Where is the problem?
THANK YOU,

To make it easy for people to help you please modify your post and use the code button </>

so your code 
looks like this

and is easy to copy to a text editor. See How to use the Forum

Your code is too long for me to study quickly without copying to my text editor. The text editor shows line numbers, identifies matching brackets and allows me to search for things like all instances of a particular variable or function.

Also please use the AutoFormat tool to indent your code consistently for easier reading.

problem is when running function " if ((dopen == true) || (dclose == true)) {

You seem to have defined dopen twice

boolean dopen = true;

and

  int dopen = (now.hour() == 7 && now.minute() == 5 && now.second() == 5);

Try removing the "int" from the line

...R

So, twice a day (but just for one second), one of these variables will be true and 'door' and 'window' will be set low for only one second... is that what you want? I doubt it.

  int dopen = (now.hour() == 7 && now.minute() == 5 && now.second() == 5);
  int dclose = (now.hour() == 22 && now.minute() == 21 && now.second() == 30 );
  if ((dopen == true) || (dclose == true)) {
    digitalWrite(door, LOW);
    digitalWrite(window, LOW);
  }
  else {
    digitalWrite(door, HIGH);
    digitalWrite(window, HIGH);
  }

I need to give a pulse of one second for opening and a pulse of one second for closing
