Countdown To The Royal Wedding Begins

William and Kate will be man and wife in less than 24 hours, and fans waiting outside Westminster Abbey for the Royal Wedding, are counting down the minutes!

Here is a timeline for the big event:

11:00am - The Marriage Service

12:15pm - William & Kate's Carriage Procession

1:25pm - The Queen and the married couple appear on the Balcony

1:30pm - The UK Royal Air Force flies over the crowd

Prince William and his bride will leave Westminster Abbey in an open top 1902 State Landau and will arrive at Buckingham Palace 20 minutes later. For those not able to get close to the action, the ceremony will be shown on big screens outside the coffee shop at Balmoral Castle, near Ballater, Aberdeenshire. We'll, of course, be showing it, too!

X17online will feature LIVE video coverage of the wedding tomorrow, beginning at 1:30 am PT. Log on then!
