Make a note. Next Wednesday. October 23 2013. That's the day Prince George will be christened, it has been revealed.
There will be no pomp or ceremony, just a small private affair in in front of close family members and friends of parents William and Kate.
They will be joined by the Queen, Duke of Edinburgh, Princes Charles and Harry, the Duchess of Cornwall and the Middletons in the Chapel Royal at St James's Palace at 3pm.
Three months after he was born, Prince George will be christened in the small chapel where Princess Diana lay before her funeral instead of the traditional setting of Buckingham Palace.
The Archbishop of Canterbury will conduct the service and George will wear a replica of the lace and satin christening gown made for Queen Victoria's eldest daughter Victoria in 1841.
In a statement, Kensington Palace said: "The christening of Prince George will take place on Wednesday 23rd October at the Chapel Royal, St James's Palace.
"Prince George will be baptised by the Archbishop of Canterbury, the Most Reverend Justin Welby. "The service will start at 1500hrs and will last approximately 45 minutes."
The christening will take place just over three months since George was born.
The guest list has not been released but Kensington Palace has said in the past that 'close members of both families' will attend.
In the past, senior royal babies - the Queen, the Prince of Wales and William - have been christened at Buckingham Palace. But William and Kate have chosen the Chapel Royal, where the coffin of the Duke's mother, Diana, Princess of Wales, lay before her funeral.
Following the christening a historic picture will be released showing the Queen with three future monarchs - Charles, William and George.
There has also been speculation about who the Cambridges might choose to be their son's godparents, with close friends like Hugh van Cutsem and Thomas van Straubenzee in the running.
