My German Schengen Visa allows me to enter the country on Dec 12. Can I book my departure flight on late evening of Dec 11th?

Question

So I applied for the German Schengen visa recently and got approved. the thing is, in my document I asked for a period of about 20 days from December 11th 2021 to Jan 2022. But the visa came back with "FROM: 12-12-2021". Can I still keep my original itinerary, which has the departure flight on evening Dec 11 (departs at 20:00 from Toronto - it will takes 7-8hrs to land in Frankfurt) and land on the early morning of Dec 12? Would the border police nitpick that part and not allow me to enter my plane?

Answer 1

Your departure date (2021-12-11 20:00 EST) is 2021-12-12 02:00 CET.

The date of arrival (and departure) on the corresponding passport stamp is what counts.

I don't recall any regulation that deals with any timezone difference between WET (Portugal), CET and EET (Finland/Greece), so assume that the local timezone of the country that issues the passport stamp is what counts.
