It has been revealed that St George's Day - April 23 - is "close" to the Duchess of Cambridge's due date.
According to sources of The Sun, "There's no certainty with due dates of course but the Duchess is working off a date around St George's Day and it would be a lovely patriotic coincidence if he or she were born then," the source said.
St George's Day is recognised as the patron saint of England's feast day, but not marked with a public holiday.
If the royal baby does arrive on St George's Day, it could reignite calls for April 23 to become a public holiday.
The idea has been raised in parliament every year since 2006. Most other countries have a day off to celebrate their national Saint, such as St Patrick's Day in Ireland.
Just as Kate and William did with Prince George and Princess Charlotte, the royal parents have reportedly decided not to find out the gender of their baby, The Sun also reports.
It's also claimed she'll give birth at the Lindo Wing of St Mary's Hospital in London, just as she did with her two other babies.
Despite the Duchess of Cambridge laying low during the early stages of her third pregnancy due to suffering from hyperemesis gravidarum, 2018 has been Kate's busiest year for royal engagements.
According to one royal expert, this increase in engagements is far from coincidental. Instead, it's more likely to be a conscious choice on the Duchess's part, to account for the time she took off earlier in this pregnancy – and for the time she'll take off following the birth.
