The plans present something of a conflict, however, for Prince Harry’s older brother, Prince William.

Prince William is president of the English Football Association, and May 19 is the date of the F.A. Cup final, one of the biggest English soccer matches of the year. (He presented the trophy to this year’s winner, Arsenal.)

The May nuptials will be the first royal wedding since April 29, 2011, when Prince William and Catherine Middleton were married at Westminster Abbey in London.

Like his brother’s wedding, Prince Harry’s is expected to draw a crowd: Immediately after the date was announced on Friday, rooms in hotels in and around Windsor were disappearing from websites like Booking.com and Expedia.
