The due date for what might be this year’s most-anticipated bundle of joy has been revealed. The Duchess of Cambridge and Prince William expect their first child on July 13, the Daily Mail reports.

An unnamed source told the British tabloid that Kate Middleton announced the due date to family and friends during a recent BBQ.

“They were all discussing the fact that Kate’s baby is due to be born on July 13. Everyone was excited,” said the source.

While the royal couple had already announced that they expected their baby to be born in July, the Daily Mail's report provides a precise date.

The baby's due date falls during the middle of the four-day Coronation Festival that will be held July 11-14 to mark the 60-year anniversary of the Queen’s crowning.

Middleton is expected to deliver the baby with Prince William by her side at the private Lindo Wing of St. Mary’s Hospital in Paddington. The Duchess will be in the care of gynecologists, Alan Farthing and Marcus Setchell, according to reports.

In response to the Daily Mail's report, a Palace spokesperson said, “We have only said that the Duchess is due in July. Anything further would be speculation.”

Earlier this month, the U.K. Mirror’s Sunday People reported that Prince Harry had revealed the unborn baby's gender.

“Harry has been telling everyone Wills and Kate are having a boy and how thrilled he is at the prospect of having a little nephew,” said a source, who also claimed that the royal family wasn't keen on revealing any baby names. “They’re really working hard on baby names and think they have it sorted but they won’t reveal anything to anyone -- not even Harry.”

Before Harry’s slip, rumors circulated that Middleton was expecting a baby girl who would be named Elizabeth Diana Carole in honor of the late Princess Diana, the Queen and Middleton’s mother. Middleton fueled rumors after she was caught saying, “Thank you, I will take that for my d… for my baby,” while accepting a teddy bear from a fan at an event in March, according to reports.
