SEQUENCE:0
STATUS:CONFIRMED
SUMMARY:Mortgage Payment
TRANSP:TRANSPARENT
END:VEVENT

What did you expect to happen?

the event is schedule for Monday

What actually happened?

, but shows on Sunday, repeating

full day events are local timezone only. so altho the event LOOKS like DST (at the time it was created),
it is DST/STD time insensitive.

this was the startofday/endofday discussion had earlier

Is this a typo: BEGIN:VALENDAR?

[KristjanESPERANTO]

But that seems not to be the cause. I'm looking into it.
