What happens during the 'royal mourning period' now the public mourning period is over

ok.co.uk:

Queen Elizabeth II's state funeral took place on Monday 19 September, with the late monarch being laid to rest in The King George VI Memorial Chapel at Windsor Castle.

Her Majesty's funeral marked the end of a 12-day mourning period which started on 8 September - the day she passed away at Balmoral Castle.

The Royal Family are observing their own period of mourning though, which will end seven days after the Queen's funeral. Buckingham Palace released a statement, saying: “Following the death of Her Majesty the Queen, it is His Majesty the King’s wish that a period of royal mourning be observed from now until seven days after the Queen’s Funeral. “Royal mourning will be observed by members of the royal family, Royal Household staff and representatives of the Royal Household on official duties, together with troops committed to ceremonial duties.” During this time, members of the Royal Family are not expected to carry out official engagements and flags at royal residences will remain at half-mast until 8am after the final day of royal mourning.

When the Royals entered a royal mourning period in 2021 after the death of the Queen's husband, Prince Philip, the family continued to attend suitable engagements and when appropriate, they wore mourning bands.
