Kate made an unexpected change in her schedule and attended an earlier garden party than expected. The garden party she was scheduled to attend was in conjunction with the Red Cross, an organization of which her family, and purportedly Kate herself, are strong supporters. It isn't known why she changed her plans, although, her attendance did coincide with the Duke of Edinburgh's 93rd birthday. Earlier in the day, Kate had been in Greenwich for an America's Cup event with Ben Ainslie.
