Calculates when a legal deadline ends in Germany (Fristende, due date) under §§
Calculates when a legal deadline ends in Germany (Fristende, due date) under §§ 187-193 BGB, the German Civil Code: event vs commencement start (§ 187), end by days/weeks/months/years including a missing day of month (§ 188), and postponement to the next working day when it falls on a Sunday, Saturday or public holiday (§ 193). With a federal state the statewide holidays are honoured, without one only Sunday/Saturday; that limit is stated. Returns an end date, not a count of working days.
