Use java date formats.

SimpleDateFormat inFormat = new SimpleDateFormat("dd-MM-yyyy");
Date date = inFormat.parse(input);
SimpleDateFormat outFormat = new SimpleDateFormat("EEEE");
String goal = outFormat.format(date);

You can use Calendar

            Calendar calendar = Calendar.getInstance();

            calendar.setTime(date_your_want_to_know);

            String[] days = new String[] { "SUNDAY", "MONDAY", "TUESDAY", "WEDNESDAY", "THURSDAY", "FRIDAY", "SATURDAY" }

            String day = days[calendar.get(Calendar.DAY_OF_WEEK)];

String[] days = new String[] {"", "SUNDAY", "MONDAY", "TUESDAY", "WEDNESDAY", "THURSDAY", "FRIDAY", "SATURDAY" } – Milon May 01 '16 at 11:32

String day = days[calendar.get(Calendar.DAY_OF_WEEK)]; we should chage above line to String day = days[calendar.get(Calendar.DAY_OF_WEEK) - 1]; //because array of index start from 0 – Dinesh Sarma May 31 '21 at 15:18
SUNDAY is not always the first day – Nininea May 24 '22 at 08:59

Just use a single line of code:

android.text.format.DateFormat.format("EEEE", date);

This is the best approach in my opinion. Does exactly what the author of the question asked for and is a single line. – Forke Nov 15 '16 at 18:10

On @vivek's answer add "-1" at calendar.get(Calendar.DAY_OF_WEEK), since it returns numbers from 1 to 7 but the String array is indexed from 0 to 6.

calendar.setTime(date_your_want_to_know);

String[] days = new String[] { "SUNDAY", "MONDAY", "TUESDAY", "WEDNESDAY", "THURSDAY", "FRIDAY", "SATURDAY" }

String day = days[calendar.get(Calendar.DAY_OF_WEEK)-1];

Try this code. Hope it will work. This is worked for me.

public String daysNameOfWeek(String inputDate){

    DateFormat df = DateFormat.getDateInstance(DateFormat.MEDIUM, Locale.UK);
    try {

        Date date = df.parse(inputDate.trim());
        SimpleDateFormat outFormat = new SimpleDateFormat("EEEE");
         daysName  = outFormat.format(date);

    } catch (ParseException e) {
        e.printStackTrace();
    }


    return daysName;
}

Calendar date = Calendar.getInstance();
String dayToday = android.text.format.DateFormat.format("EEEE", date).toString();
TextView myTextView = findViewById(R.id.myTextView);
myTextView.setText(dayToday);

While this piece of code may provide a solution to the question, it's better to add context as to why/how it works. This can help future users refer to and eventually apply this knowledge to their own code. You are also likely to have positive feedback/upvotes from users, when the code is explained. – Amit Verma Mar 03 '21 at 07:34

First convert the date string to a Date using SimpleDateFormat.

Then make a Calendar instance from that date.

Finally, retrieve the day of week from the Calendar using the get(Calendar.DAY_OF_WEEK). This will give you an integer between 1 to 7 representing the day of the week. You can simple map this to an array of Strings to get the days.

Below method will return the day by passing the date in String format. null is returned if exception occurs.

private String getDay(String date_in_string_format){        
        DateFormat df = DateFormat.getDateInstance();
        Date date;
        try {
             date = df.parse(date_in_string_format);
        } catch (Exception e) {
            Log.e("Error:","Exception " + e);
            return null;
        }
        return new SimpleDateFormat("EEEE").format(date);
    }

Hope it helps.
