It was sent on the 8th in the GMT time zone. That could be the 7th or 9th for you, depending on where you live. Let's say you live in Australia (UTC+10) and the vendor lives in California (UTC-8). The vendor marks a package as in transit at noon local time, February 8. That's 6 am, February 9 for you, so the vendor sent the package on Feb 8 his time but Feb 9 your time.
