I logged into my online banking this morning, after having a rough night and spending a wee bit too much money than usual, to see my first payment from google already through? Is it usual for payment to come this early? From what I understood on the calendar thing payment wouldn't be here until like the 5th of October.
Depends entirely on the country you live in, I believe. I'm from the UK and my payments are always sent between the 30th, and the 5th of the month. Never sooner, nor later.
My payments have been issued on the following days: 23 (x2) 24 (x3) 26 (x1) 27 (x1) This is for a U.S. bank account. They normally appear in the bank balance the next day, unless there is a holiday or weekend coming up. The 5th of October (or any payment's following month) is only meant as a day when you can request a reissue if you haven't received the EFT payment yet. You can read more about that here.
