Meghan also did not appear before the Windsor wedding of Lady Gabriella, who is 52nd in line, only 12 days after her birth.
In today's celebration, the queen is expected to be accompanied by members of her family to view the ceremony from a slide in Horse Guards Parade, London.
Those who are expected to participate are the royal colonels, all on horseback, will accompany the queen: the Prince of Wales, Colonel of the Welsh Guards; the Princess Royal, Colonel of the Blues and Royalists; the duke of Cambridge, colonel of the Irish guard and the duke of York, colonel of the grenadier guards.
The Duke and Duchess of Sussex, in addition to the Duke and Duchess of Cambridge, are also expected to be present.
The queen, who celebrated her 93rd birthday in April, will watch the Trooping ceremony and also inspect the rows of guardsmen in their scarlet tunics and bear skins.
Among the expected soldiers are the identical twin Ben and Thomas Dell, both 21, from Bath in Somerset. Thomas is in the Grenadier Guards while Ben will be at the Household Cavalry
The Duke of Edinburgh, who is celebrating his 98th birthday on Monday, has stopped official public duties and is not expected to attend.
During the ceremony, involving around 1,400 soldiers, the queen travels to and from Horse Guards Parade in a procession accompanied by a Sovereign's Household Cavalry consisting of the Life Guards and Blues and Royals, in their silver and gold breast plates and plumed helmets.
The mass bands of the Household Division will provide musical support during the day and also participate in the King & # 39; s Troop Royal Horse Artillery which, after the parade, fires a 41-gun greeting in Green Park on the occasion of the Queen's official birthday.
After the ceremony, the royal family returns to Buckingham Palace and gathers on the balcony to view the RAF tour.
More than 20 aircraft will participate, including modern jets and historic aircraft, while the Red Arrows will be the final.
Among the soldiers expected for the splendor are twins Ben and Thomas Dell, both 21, from Bath, Somerset.
Guardsman Thomas will be with the Grenadier Guards and Trooper Ben will be with the Household Cavalry.
It will be the first time that Thomas has colored his troops, but Ben's third time is involved in the splendor of the event.
& # 39; Everything is a competition between the both of us, & # 39; said Ben.
& # 39; At home, since we were very young, all the way up to now, it is always a competition of who is the better. It's a lot of fun. & # 39;
The 21-year-old twins will be part of the soldiers, along with 400 musicians from the mass bands.
The Grenadier Guards, recognized for their scarlet tunics and bears' hats, perform both an operational role and duties at Buckingham Palace and Windsor Castle.
The ridden regiment of the Household Cavalry, with which Ben serves, supplies ceremonial troops for all state affairs, including the opening of the Parliament.
As a Grenadier Guard, Thomas was deployed to Iraq to work with the US coalition and returned to the UK just before Christmas.
Trooping the Color arose from traditional preparations for the fight.
Colors, or flags, were worn by the soldier, or & # 39; truncated & # 39 ;, so that they could be seen and recognized by the soldiers.
In the 18th century, guardians of the royal palaces gathered daily at Horse Guards Parade to comfort & # 39; the colors & # 39; and in 1748 it was announced that the parade would also mark the official birthday of the Sovereign.
