Help and Advice Needed

Hi everyone,

I received my Norway Schengen visa today and I am unsure about one point.

The visa is valid from 16 June to 5 July. In my application, I stated that I would travel on 16 June and return on 20 June, and I had already booked my flights and accommodation based on those dates.

However, 10 days after submitting the application, my return flight was cancelled by the airline. They have now rebooked me on a flight returning on 21 June, as there are no other suitable flights available on 20 June. I also cannot return one day earlier on 19 June, because I am presenting at a conference that day, which is the main purpose of my travel.

The issue is that the visa states “duration of stay: 5 days”. If I enter on 16 June and leave on 21 June, that would be 6 calendar days, even though the visa itself is valid until 5 July.

Would this be considered overstaying because the duration of stay is only 5 days, or does the validity until 5 July allow me to leave on 21 June?

I would really appreciate any advice, especially from anyone who has experienced a similar situation.
