Date Format

You can create calculated column instead.

For example:

1.      you have the date column like “Created”

2.      Create new calculated column, type the formula like “TEXT(Created, “dd-mmm-yyyy”)”

Now you can use this column displayed in your view.

The date format is dictated by Locale. This is effected by what locale the site is created is. It can be changed on an individual basis by clicking on the User ID drop down in the top right -> MySettings -> My Regional Settings -> Change the Locale.
