The wedding of Prince Harry and Meghan Markle is set to be one of the biggest events of the year for royal family enthusiasts.
Luckily for Australians, the ceremony is at the prime time of 9pm on Saturday.
If you're planning a royal wedding party, here are all the key times and places to watch it.
Important times for the wedding
The wedding ceremony will be held in St George's Chapel, inside the grounds of Windsor Castle.
Guests will begin arriving at Windsor Castle about 6pm AEST (9am local time). More than 2600 members of the public have been invited to watch the wedding from inside the grounds of the castle, including 1200 who were chosen for their community or charity work.
The main wedding guests – the 600 or so people who were invited to the ceremony inside the chapel – will begin arriving from 6.30pm AEST.
Members of the royal family are expected to start arriving by foot and car around 8.20pm.
The groom and his best man – older brother William, the Duke of Cambridge – will arrive on foot shortly after their family, and the Queen herself is expected to be the last guest to arrive, just before the ceremony starts.
While the royal family is arriving at the chapel, Ms Markle and her mother, Doria Ragland, will begin their journey there for the ceremony, which starts at 9pm AEST.
The ceremony itself will take about an hour, and then the newly-married couple will take a horse-drawn carriage ride around Windsor afterwards, Kensington Palace said.
The 25-minute procession is the end of the public part of the wedding, the palace said.
The final thing you can expect to see is Prince Harry and Ms Markle leaving the castle for their reception at Frogmore House, a 17th-century country house less than a kilometre away.
