Because of different time zones and different schedules of posters, the "rule" is not day by day, but 24 hours. So today's time (as *I* see it stamped on the post time here, not sure what everyone else sees?) was about 9:30 am, whereas you posted at 8:31am. Not a biggie, but technically, an hour early.
Anyway, time for next "starter" picture, by the time stamp I get, is 8:31am Monday.
