next two weeks/nächsten zwei wochen work different then expected

If I say I say: "In the next two weeks", I mean two weeks from now, duckling, however, interpretes this as two weeks from next Monday.

The same bug applies to last two weeks/letzten beiden wochen

Start by reproducing the English and German phrases described in the issue and trace the date rules that handle “next two weeks” and “last two weeks.” Done means both phrases are interpreted relative to the current date rather than the following Monday, with regression coverage for both languages.
