The monarch will turn 78 on Saturday, but before then, he will take on a busy day in Croydon.
King Charles looked animated as he cut a special cake celebrating the two milestones - his birthday and the Surrey Street Market's 750th anniversary on Friday.
People around him clapped as the monarch showed off the large butcher knife with a laugh.

King Charles' visit to the Surrey Street Market on Saturday was to meet and celebrate the people who have shaped the market's long, long history and helped protect the vibrancy it brings to local communities.
On his arrival, the monarch was presented with a bottle of juice, and given how health conscious he is, he would have appreciated the healthy boost of energy.

Well, yes! The Surrey Street Market is one of the oldest continuous street markets, dating back to 1276, when it was granted its Royal Charter. At the time, King Edward I of the House of Plantagenet was on the throne.
So not only does the market predate the Windsors, but it is also older than the Lancasters, Tudors, Stuarts, and Hanovers!

After a fascinating visit to the BRIT School, King Charles headed to the Surrey Street Market to celebrate its 750th anniversary! A milestone? We think so.

The BRIT School for Performing Arts and Technology is a leading creative school in the UK with star-studded alumni including Adele, Tom Holland, Amy Winehouse, etc.
But the most unique aspect of the institution is that it is completely FREE to attend. It provides education to over 1,300 pupils between the ages of 14 and 19 in the fields of music, film, digital design, community arts, visual arts and design, production and performing arts, as well as a full academic programme of GCSEs and A Levels.
The school would certainly be thriving with creative energy, and what better place for an arts enthusiast (like King Charles) to visit before their special day?

The day before his 78th birthday, King Charles took on some special public engagements in Croydon.
First on the schedule was a visit to the BRIT School for Performing Arts and Technology, where he viewed a student fashion showcase.
