And Prime Minister David Cameron has confirmed that the occasion will be marked with a public holiday.
Westminster Abbey is the same place that hosted the Queen and the Queen Mother’s weddings; it was also the venue for Princess Diana’s funeral in 1997.
The prince’s private secretary Jamie Lowther-Pinkington said the couple wanted a spring wedding and felt that the abbey offered relative intimacy despite its size.
The extra day’s holiday falls in the same week as Easter Monday, giving millions of workers a three-day week.
David Cameron said, “We want to mark the day as one of national celebration, a public holiday will ensure the most people possible have a chance to celebrate on the day.”
