The prince, a helicopter search-and-rescue pilot in the Royal Air Force, is on duty at a base on an island off the coast of Wales and is expected to mark his birthday privately.
The prospect of a low-key birthday on Tuesday might appeal to the prince following his blow-out April 29 wedding at Westminster Abbey to /*Kate Middleton.*/ He is also due to travel to Canada and the United States next month on his first official overseas trip as a married man.
William's grandfather, /*Prince Philip,*/ recently celebrated his 90th birthday with a full day of official engagements.
