People Editorial Guidelines Published on June 17, 2017 06:53AM EDT It’s time for Trooping! Saturday is the annual Trooping the Color in London, which marks the formal celebration of Queen Elizabeth II’s “official” birthday. (Her actual birthday is April 21 — you can learn about why she has two birthdays here.) As usual, all your favorite royals were there to celebrate the 91-year-old monarch’s milestone. The Queen and Prince Philip, who turned 96 last week, kicked things off in a carriage.

The Duke of Edinburgh wore morning dress instead of full uniform, and sports a Household Division tie, Garter Star and Medals.

Kate wore a pink Alexander McQueen dress and matching hat by Jane Taylor while Camilla donned a cream ensemble.

The Queen also issued a solemn but ultimately uplifting message to people of Great Britain following a month of tragedies — including two terrorist attacks and a deadly apartment tower fire. “Today is traditionally a day of celebration. This year, however, it is difficult to escape a very’ sombre national mood. In recent months, the country has witnessed a succession of terrible tragedies,” she said. “As a nation, we continue to reflect and pray for all those who have been directly affected by these events,” the Queen continued. “During recent visits in Manchester and London, I have been profoundly struck by the immediate inclination of people throughout the country to offer comfort and support to those in desperate need. “Put to the test, the United Kingdom has been resolute in the face of adversity. United in our sadness, we are equally determined, without fear or favor, to support all those rebuilding lives so horribly affected by injury and loss.” She signed the message simply “ELIZABETH R” WATCH: Prince William, Princess Kate, Prince George, & Princess Charlotte Are Set To Attend Trooping The Colour After the parade, the entire royal family gather on the balcony of Buckingham Palace for the “flypast” of roaring jets. And, of course, that’s when we’ll get a glimpse of Prince George and Princess Charlotte. Trooping the Color brings out nearly every member of the royal family to celebrate the Queen’s birthday with the rest of the U.K. And it is always a day for memorable candid moments — from Prince George wagging his tongue in the window in 2015 to Prince William getting scolded by his granny the Queen for leaning down to talk to George in 2016. with reporting by PHIL BOUCHER
