Yap, is inclusive of statement date.
This was what I realised a few months ago, posted on another thread.
I had transactions incurred and posted on the statement day and they were included in the statement. The transactions were only done in the afternoon of the day. Hence I thought the statement was only generated at the end of the day.
However, recently, I checked online banking in the morning of the statement date and the statement for the month was already generated. Luckily all transactions to meet the minimum amount have already been posted. If not, I will lose out on the rebates.
To play safe, always give enough time for merchants to post their transactions. Also, don't use the card on the usual statement day as you will not know what time they will generate the statement and whether the merchant will post on the same day. Had occasions where statements were generated only on the next day instead of the usual statement date.
