The Queen's official death certificate has confirmed that on the day she died, she passed away at 3.10pm.
Just hours earlier, her doctors expressed concerns over her health and the royals raced to Balmoral to be at her side in the final hours of her life. Among them was her grandson Prince Harry, who just happened to be in the middle of a mini-tour of the UK and Germany when her health took a turn for the worse. However, he only managed to get to Balmoral at 8pm that night with his private jet flight to Aberdeen leaving Luton Airport at 5.35pm - more than two hours after the Queen had died.
The official announcement of her death came at 6.30pm that day - with the Daily Mail reporting that palace officials say King Charles personally told Harry the sad news just five minutes before the rest of the world.
It is believed that earlier in the day, Charles had told both Harry and older son Prince William to come to Balmoral as their grandmother was seriously ill.
This has led some to wonder why Harry learned of her death over three hours it took place - although it's not clear how easily contactable he was with reports also suggesting Charles does not carry a mobile phone.
However, this is what appears to have happened on that fateful day....
September 8 - lunchtime
On the day of the Queen's death, Harry and Meghan were due to appear at the WellChild Awards in London. In previous days, they had already been to Manchester and Dusseldorf.
At 12.35pm on September 8, a statement was released by Buckingham Palace saying doctors had become concerned for the Queen's health and that she was under medical supervision.
Within 15 minutes, a statement said the now King Charles and Queen Consort Camilla would be travelling to be with the Queen - and Prince William would also be going to Balmoral.
It is believed Charles and Camilla quickly reached Balmoral in the early afternoon. Princess Anne was already at her mother's side.
September 8 - afternoon
Just after 1.30pm that day, it was announced Prince Andrew, Prince Edward and Sophie Wessex would also be racing to Balmoral.
Minutes later, it was reported Harry and Meghan would be "travelling to Scotland" after changing their plans - although this was later revised to just Harry going to Balmoral.
It was reported that Harry would take the same plane from RAF Northolt as his royal relatives - but he instead travelled on a separate private jet.
Last week, the Sun alleged that Harry missed the RAF flight due to a row over whether it was "appropriate" to bring wife Meghan Markle with him.
A source told the newspaper: "Harry was so busy trying to get Meghan to Balmoral and rowing with his family that he missed the flight."
The RAF flight that took William, Andrew, Edward and Sophie to Aberdeen left Northolt at 2.39pm - and as the death certificate lists the time of death at 3.10pm, they did not make it to the Queen's beside before she passed away. They arrived at Balmoral just after 5pm.
Meanwhile, a spokesperson for Prime Minister Liz Truss confirmed she learned of the Queen's death at 4.30pm.
September 8 - evening
Harry boarded flight G-LEAX at London Luton Airport and departed for Aberdeen at 5.35pm - his flight landed at 6.47pm.
At 6.30pm, Buckingham Palace formally announced the Queen's death saying she had passed away peacefully that afternoon.
According to the Daily Mail, palace officials say Charles was able to contact his son at 6.25pm to tell him the sad news - five minutes before the rest of the world was informed.
Harry was eventually driven through the gates of Balmoral around 8pm - almost five hours after the Queen passed away.
September 9 - morning
The morning after the Queen's death, Harry was the first royal to leave Balmoral catching a British Airways flight from Aberdeen to London Heathrow around 8.30am.
An empathetic member of ground staff could be seen talking to him in the moments before he boarded the plane to leave Scotland.
He was seen putting a kind hand on her back as they chatted in what was clearly an emotional moment between the pair.
