I would be interested in the meaning of the following deadline (Frist) for submitting documents to a German Agency (Amt).
The wording in the letter is the following:
"Senden Sie uns bis spätestens zum 01.03.2021 eine Kopie der Unterlagen mit Ihrer Unterschrift zu".
Does it mean that I can submit the documents until end of the business day by email? Or do they need the documents the day before. Does "bis spätestens zum" in German language imply that the day is included or excluded? I always struggle but I tend to would say it should include per se the day mentioned.
