extra information

Thanks guys, Now i know what causes this peculiarity. So there is a disadvantage to living in Belgium🤣🤣🤣 I will try to convince my pc that i am native dutch speaking instead of French speaking, In the end it does not really matter .

try the US locale....

new SimpleDateFormat("MMM dd, yyyy", Locale.US)

or set en-US as default lang in the class

Locale.setDefault(new Locale("en", "US"));

Most likely this is just the local language settings on your computer. Take this little bit of code as an example:

SimpleDateFormat df1 = new SimpleDateFormat("dd-MMM-yyyy",Locale.ENGLISH);
Date date = df1.parse("28-oct-21");
SimpleDateFormat df2 = new SimpleDateFormat("dd-MMM-yyyy",Locale.FRENCH);
System.out.println("English: " + df1.format(date));
System.out.println("French: " + df2.format(date));

Using the same format but different languages you get different outputs. This code outputs: English: 28-Oct-0021 French: 28-oct.-0021 I don't think there is a way to change that behavior, not one that I found anyways, but if you still want to use the local language you could always remove the period (or any unwanted formatting) using the replaceAll() method of the String class:

"AUG. 18, 2013".replaceAll("\\.", "")

Which, if you output that result, would be: AUG 18, 2013
