We currently have visitors in Germany, at the airport one agent noted that our visitors will overstay for 1 day, but I feel like they made a mistake, but I am not sure.
I have attached the visa information and censored all personal data, it says it's valid from 28.02.2022 until 27.05.2022 (89 days). They arrived at 28.02.2022 in FRA in the morning and will leave on 27.05.2022 in the evening (departure is definitely before midnight). The agent noted they normally would have to leave on 26.05.2022. I don't quite understand where I am wrong, maybe someone can help.
