tl;dr

LocalDate
.now( 
    ZoneId.of( "America/Edmonton" ) 
)
.toString()

2025-01-23

Modern Java uses java.time

For a date-only value, use LocalDate class.

Your desired format of YYYY-MM-DD complies with the ISO 8601 standard used by default in the java.time classes for generating/parsing text. So no need to specify a formatting pattern. You can parse directly.

LocalDate ld = LocalDate.parse( "2025-01-23" ) ;

And you can generate text with a simple call to toString.

LocalDate today = LocalDate.now( ZoneId.of( "Africa/Tunis" ) ) ;
String output = today.toString() ;

2025-01-23

DateFormat dateFormat = new SimpleDateFormat("yyyy-MM-dd");
Calendar cal = Calendar.getInstance();
String dt = dateFormat.format(cal.getTime());

Use MM instead of mm.

You need "MM" for month. "mm" is for minutes.

See http://docs.oracle.com/javase/6/docs/api/java/text/SimpleDateFormat.html

You need to use capital MM and not mm. Lower case 'mm' is for minutes and not for months.

So, your code would be :

DateFormat df = new SimpleDateFormat("yyyy-MM-dd");

Month is retrieved by MM, not mm.

DateFormat df = new SimpleDateFormat("yyyy-MM-dd");

Refer to SimpleDateFormat JavaDoc:

M Month in year

You have used mm which means minutes. Use capital MM instead.

You can find all date and time pattern symbols on the SimpleDateFormat Javadoc page.
