How to change image in main-activity based on date in android application

Looking for an android application, that needs to change the image after day by day.

Example: If system date=01.01.2021 then image1 should be displayed else image2 should be displayed.

This is my android source code:

package com.wavedevelopers.chat;

import androidx.appcompat.app.AppCompatActivity;
import java.util.Calendar;
import java.util.Date;

import android.os.Bundle;
import android.widget.ImageView;

public class MainActivity extends AppCompatActivity {


    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        ImageView imageView;

        Calendar cal = Calendar.getInstance();

        Date now_date = null;
        cal.setTime(now_date);

        imageView = (ImageView)findViewById(R.id.content);

        if(cal.get(Calendar.DAY_OF_WEEK) == Calendar.MONDAY)
        {
            imageView.setImageResource(R.drawable.a1);
        }
        else if(cal.get(Calendar.DAY_OF_WEEK) == Calendar.TUESDAY)
        {
            imageView.setImageResource(R.drawable.a2);
        }


    }
}

        }
        else if(dayOfMonth == 1) {
            System.out.println("It's the first of the month")
        }

    }
}
