Steps to reproduce the bug

1. I open my camera app and read a QR code

BEGIN:VCALENDAR
VERSION:2.0
PRODID:-//John Nash//ICS Tool//DE
BEGIN:VEVENT
UID:uid-dn5vfvgeq@john-nash.de

END:VEVENT
END:VCALENDAR

2. I open it with fossify calendar
3. fossify calendar offers me an input mask where everything is imported correctly - but the date
4. In this example above the date should be 2026-07-23...but fossify calendar uses 2026-08-23....so: one month off

Expected behavior

I expect to use DTSTART and DTEND according to the import

Actual behavior

...one month off

2026-07-23 becomes 2026-08-23
