Incorporating button into Servo Loop. Help!

Projects General Guidance

Someone else gave me this code which allows the button to start the cycle but the servo only goes to 180 when I hit the button. Any ideas on how to allow the 24 hour cycle to play out but be overridden by pressing the button?

#include <Servo.h>
Servo myservo;
const int BUTTON_PIN = 7;
const int SERVO_PIN  = 9;

void setup(){
  myservo.attach(SERVO_PIN);
  Serial.begin(9600); 
  pinMode(BUTTON_PIN, INPUT_PULLUP);
  myservo.write(0);
  } 
  
void loop(){
  if(!digitalRead(BUTTON_PIN))
  {
    myservo.write(180); //(open?)
    delay(6000);
    myservo.write(0);
    delay(86400000);
  }
}
