sorry can I ask wisdom on one more point of detail. If I have a flight landing at say 5.00pm on a Sunday, then according to gov.uk I can take a Test to Release test on the 5th full day. That would be the Friday. The question is can I take the test on the *morning* of the Friday? Or does it have to be taken after 5.00pm on the Friday (to allow five full 24 hour days)?
