Because we see time moving forward in a stream that cannot be reversed, the royal wedding is now “behind” us.

Below is the plan for the royal wedding, which, in case time turn around or someone later needs to study the historical record, we will leave in place.

Official guests will start arriving around 9:30 a.m., local time, on Saturday May 19.

Then Meghan Markle and Prince Harry of Wales are getting married at noon.

After the wedding, about 1 p.m. local time, they are expected to make a procession that will last about half an hour.
