If you use Excel date arithmetic, you will find it was 30 days to the second. Q did not err.
Lots of people are saying it’s 31 because the post from Q was July 25 and the date of death was Aug 25, to the second. That’s exactly 1 month, but in days it’s 31.
I’m not sure if it’s an important detail. I was responding to a post where it was asked if it was 30 or 31.
The much more important detail I think is the timestamp.
