Note: Note that dates in m/d/y or d-m-y format, if the separator is a slash (/), use the m/d/y format for the Americas. If the separator is a bar (-) or dot (.), The European d-m-y format is used. To avoid potential errors, you should use the Y-MM-DD format whenever possible or use the date_create_from_format() function.
