Description

From manual page: https://php.net/class.intldateformatter

The documentation for the relative dateType constants only mentions support for yesterday, today and tomorrow. But in locales that have words or common expressions for "the day before yesterday" and "the day after tomorrow", those words/expressions will be returned. So "vorgestern" and "übermorgen" will be returned when using de_DE. Worth to be mentioned in the docs?

Example code:

echo IntlDateFormatter::formatObject(
    date_timestamp_set((new DateTime()), strtotime('tomorrow + 1 day')), 
    [IntlDateFormatter::RELATIVE_LONG, IntlDateFormatter::NONE ],
    'es_ES'
    );

==> pasado mañana
