Indeed... 7 days BEFORE the end of the month is BEFORE the 24th, hence the 23rd... As it always has been.
But even when it was in the OM-A, it didn't say that- it said with 7 days notice.
If I give you 7 days notice, today is day one.
Yes they usually beat that by a day or two, and then when they actually stick to the exact 7 days, threads like this crop up.
So, they'd be better off just sticking to the 7 days, and not exceeding requirements, as it only causes people to whinge.
Of course, that means we as a group have shot ourselves in the foot, but it wouldn't be the first time.
