Nov 1 is wrong. If it was ever correct, it was way in the past.
The system will calculate based on Month and Year, so 1st day of the 24th month should work when it processes the app - you'd be 3/24 in its calculations. If you have to recon or otherwise have a human look, DPs are that they calculate to the day as listed in the CR.
IIRC Experian doesn't list the day on the reports, just month and year. So speculation for a while was for people who only have EX pulled that they were x/24 on the 1st of the month. But positive DPs for others that didn't have EX pulled were found. So perhaps that is part of why they calculate that way rather than creating separate rules for each CR being read.
I'm a bit cautious so for me I'd apply 10/2 at the earliest anyway, but since it's so close, if I didn't have a deadline expiring, I'd just wait for 10/5. If one can't wait, worth the risk before and then if not system approved, recon on the 5th. Very slim chance a rep will cite Nov 1 as the drop off, but if so, HUCA.
