Kensington Palace said in a series of tweets Sunday that the service will begin at 12 p.m. GMT, or 7 a.m. EST, May 19 at St. George's Chapel at Windsor Castle in Windsor, England.
"The Dean of Windsor will conduct the service and The Archbishop of Canterbury will officiate as the couple make their vows," the palace wrote.
Prince Harry and Markle will take a carriage ride through Windsor after tying the knot. The procession, which begins at 8 a.m. EST, will take the couple through Windsor Town before returning to Windsor Castle along the Long Walk.
"They hope this short journey will provide an opportunity for more people to come together around Windsor and to enjoy the atmosphere of this special day," the palace said.
Prince Harry and Markle will then celebrate with their guests at a reception at St. George's Hall. Prince Harry's father, Prince Charles, will host a private evening reception for the couple and their close friends and family.
"They are looking forward to the day and to being able to share their celebrations with the public," the palace said.
Prince Harry and Markle got engaged in November after more than a year of dating.
The pair attended their first award ceremony as a couple this month, stepping out to the Endeavor Fund Awards in London.
