The Princess of Wales is expected to join the Royal Family at the Remembrance Day service in November, with hopes that she will return to public life soon.
Kate, 42, has made just two public appearances since her cancer diagnosis earlier this year.
But after a quiet summer at Anmer Hall in Norfolk, she begins to think about the months ahead, The Times has reported.
The Princess of Wales is believed to have set her sights on attending the national memorial service at the Cenotaph on November 10.
There are also said to be plans for her annual television broadcast of the carol service ‘Together at Christmas’ from Westminster Abbey in December.

This comes as Kate has been meeting more frequently with her private secretary, Tom White, and the Waleses’ communications secretary, Lee Thompson, to plan for the future.
However, no firm date has been set for Kate’s return to public life, nor have any appointments been confirmed in her diary.
It has also been confirmed that she will not be accompanying her husband William to Cape Town in early November for this year’s Earthshot Prize ceremony.
Five months ago, Kate publicly announced that she had been diagnosed with cancer and was undergoing “preventative” chemotherapy.
“I am doing well and getting stronger every day by focusing on the things that help me heal; in my mind, body and soul,” she said at the time in a highly emotional and unprecedented video message.
This followed Kate’s major abdominal surgery in January, which saw her spend two weeks at the London Clinic in Marylebone.
She made her first public appearance since the shock announcement in June, when she joined the royal family to celebrate the King’s official birthday.
Her attendance at Trooping of the Colour was uncertain after she missed the final rehearsal the weekend before the event, with confirmation that she would be attending only being given at 6pm the night before.
The world watched as Kate stepped out in a stylish monochrome Jenny Packham dress with a statement bow, styled like Eliza Doolittle at Trooping the Colour in June.

In her second public appearance, the mother of three visited Wimbledon with her daughter, Princess Charlotte, and her sister, Pippa Middleton.
She was greeted with a standing ovation when she entered the Royal Box during the tennis tournament in July.
The princess passed the trophy to Carlos Alcaraz, who defeated Novak Djokovic in three sets on centre court.
Before Kate and Charlotte took their seats in the Royal Box, they met female tennis stars, including 21-year-old Emma Radacanu, who all presented Kate with a bouquet of flowers.
US Open winner Raducanu said it was “amazing” to have Kate’s support and “to see her here so healthy and happy”.
Kate, who enjoys attending sporting events and showing her support for athletes, also made a surprise appearance alongside Prince William earlier this month with a star-studded message for Team GB.
Wearing a classic black and white striped top, Kate beamed: ‘From everyone watching at home, congratulations to Team GB.’
The Prince of Wales, wearing an official blue Team GB shirt, added briefly: “Well done Team GB, you are an inspiration to us all.”
The news that Kate may resume her public duties in the autumn comes after it was announced yesterday that the King’s health is also ‘very positive’.
King Charles was diagnosed with cancer in January after undergoing treatment for an enlarged prostate.
The King and Queen are preparing for a major trip to Australia and Samoa in the autumn, their first major foreign trip since news of Charles’ cancer broke.

There will be time for rest in Australia and Samoa, with not too many back-to-back meetings to take into account the time difference and a hoped-for trip to New Zealand cancelled to reduce travel costs, but Charles’s schedule is still expected to be ‘quite full’
“Health must remain the number one priority, although the development is positive,” said a source.
Camilla also gave an insight into the King’s treatment this week as she opened a new cancer centre in Bath and revealed he was ‘doing really well’.
The king was out of public view for about three months after he was diagnosed with cancer in January.
In April he returned to work and visited a cancer centre in London, where he met other patients.
The King’s aides took the opportunity to point out that not all recovery programs for cancer patients are the same.
In the months that followed he had a number of high-profile meetings, including the 80th anniversary of D-Day in Portsmouth and Normandy, Trooping the Colour, the forthcoming Japanese state visit, a brief visit to Jersey and Guernsey, the appointment of a new Prime Minister after Labour’s landslide general election and the official opening of Parliament.
