Formatting a calendar date

I just want the date to show up like so:

Saturday, May 26, 2012 at 10:42 PM

Here's my code so far:

Calendar calendar = Calendar.getInstance();
String theDate = calendar.get(Calendar.MONTH) + " " + calendar.get(Calendar.DAY_OF_MONTH) + " " + calendar.get(Calendar.YEAR);

lastclick.setText(getString(R.string.lastclick) + " " + theDate);

This shows the numbers of the month, day, and year, but there's got to be a better way of doing this? Isn't there some simple way of doing this like using PHP's date() function?

I use this solution which is a mix of the other answers and also includes time

You can customize the DateFormat.SHORT parts to other constants to show more/different details

Short leads to this on my device: 17/07/2021 04:11

You can simply pass Calendar.getInstance() to get the current time

fun formatDateTime(calendar: Calendar):String{
    val formatter = DateFormat.getDateTimeInstance(DateFormat.SHORT,DateFormat.SHORT)
    formatter.timeZone = calendar.timeZone
    return formatter.format(calendar.time)
}

Even simpler answer:

SimpleDateFormat.getDateTimeInstance().format(cal.getTime())

For me this works perfectly:

val cal = Calendar.getInstance()

val pattern = "EEEE, MMMM d, yyyy 'at' h:mm a"
val primaryLocale = getLocales(resources.configuration).get(0)
val dateFormat = SimpleDateFormat(dateFormatPattern, primaryLocale)

val formatedDate: String = dateFormat.format(cal.time)

This is actually a fairly subtle problem to get right, and I've not seen another answer here on SO that addresses both:

  • The Calendar's time zone (which means that it might be showing a different date than local)
  • The device's Locale (which affects the "right" way to format dates)

The previous answers to this question ignore locale, and other answers that involve conversion to a Date ignore the time zone. So here's a more complete, general solution:

Calendar cal = Calendar.getInstance(); // the value to be formatted
java.text.DateFormat formatter = java.text.DateFormat.getDateInstance(
        java.text.DateFormat.LONG); // one of SHORT, MEDIUM, LONG, FULL, or DEFAULT
formatter.setTimeZone(cal.getTimeZone());
String formatted = formatter.format(cal.getTime());

Note that you need to use java.text.DateFormat here, not Android's own (confusingly-named) android.text.format.DateFormat.

Calendar calendar = Calendar.getInstance();
SimpleDateFormat format = new SimpleDateFormat("EEEE, MMMM d, yyyy 'at' h:mm a");
System.out.println(format.format(calendar.getTime()));

Running the above code outputs the current time (e.g., Saturday, May 26, 2012 at 11:03 PM).

See the Android documentation for SimpleDateFormat for more information.

The format specification of SimpleDateFormat is similar to that of PHP's date function:

echo date("l, M j, Y \a\\t g:i A");

You're right. Compared to the Java code, the PHP code is much more succinct.

Use the below to format the date as required. Refer this LINK

 Calendar calendar = Calendar.getInstance();
 lastclick.setText(getString(R.string.lastclick) + " " + String.format("%1$tA %1$tb %1$td %1$tY at %1$tI:%1$tM %1$Tp", calendar));

Where %1$tA for staurday, %1$tb for May,

and so on...
