Hard Times

The sign on Aziraphale's shop reads: "Bookshop Opening Hours - I open the shop on most weekdays about 11:30 or perhaps 10 am while occasionally I open the shop as early as 8, I have been known not to open until 1, except on Tuesday, I tend to close about 5:30 pm, or earlier if something needs tending to. However, I might occasionally keep the shop open until 8 or 9 at night. You never know when you might need some light reading. On days that I am not in, the shop will remain closed. On weekends, I will open the shop during normal hours unless I am elsewhere. Bank Holidays will be treated in the usual tradition, with early closing on Wednesdays, or sometimes Fridays. (For Sundays see Tuesdays). A. Z. Fell, Bookseller.

In 539, when Crowley and Aziraphale are knights, they wear suits of armour. The suits of armour they wear, plate armour, do not match with armour of the time. Plate armour has been reliably traced to the beginning of the 15th century, 900 years after 539.

The opening credits sequence doesn't start until 28 minutes 40 seconds in, almost exactly halfway through the episode run time. In all other episodes, the intro starts 2-6 minutes in.
