An alleged Islamic State (IS) supporter from East Lancashire accused of sharing details of Prince George's school on social media will now face trial in May.
Husnain Rashid, 31, made the post about the young royal on messaging app Telegram, it is alleged.
The British national, of Leonard Street, Nelson, Lancashire, also allegedly planned to travel to Syria to join IS.
He was arrested on November 22 and charged with preparing acts of terrorism and assisting others to prepare acts of terrorism.
Mr Justice Haddon-Cave previously set a four-week trial at Woolwich Crown Court to be heard before Judge Andrew Lees from April 30.
But during a hearing at the same court on Friday afternoon, Judge Lees agreed to move the trial back to May 14.
A plea hearing will instead go ahead on the original trial date of April 30.
Rashid attended the hearing on Friday after being brought from Wandsworth prison.
