"And hopefully we're doing Jo proud by doing the things that she would have been doing".
More than 108,000 get-togethers are happening across the country, according to the event's website, including bake-offs, barbecues and games of football.
Jo Cox was campaigner on issues relating to the Syrian Civil War, and founded and chaired the all-party parliamentary group Friends of Syria.
The Batley and Spen MP was shot and stabbed by far-right terrorist Thomas Mair during the EU Referendum campaign on June 16 a year ago.
"I remember running to the train just thinking, just be OK, like if you're injured, if you're hurt, we'll be OK, we'll put you all back together, just don't die".
It was organised by Mrs Cox's husband Brendan on the weekend of the anniversary of her death.
Kim Leadbeater, Mrs Cox's sister, said the reaction to The Great Get Together was "amazing".
"Jo's maiden speech in the House of Commons had that memorable phrase "we have more in common than anything that divides us", so that's a pretty good principle or all of us to try and live our lives by".
ON the very weekend that communities are encouraged to come together to honour the memory, and legacy, of Jo Cox, it is humbling that Bernard Kenny - the pensioner badly injured as he rushed to the aid of the dying MP - is awarded the George Medal for his bravery and heroism. "We should come together to celebrate the strength, kindness and unity of our communities".
Speaking to CNN's Christiane Amanpour this week, Cox said he wrote the book for those "who wanted to learn more about her - people who felt she stood for something".
They are inspired by her belief that we had more in common with each other than what divides us.
Mair was jailed for life after being convicted of her murder at the Old Bailey in November previous year. "So it's not as if today is actually very different for us in lots of ways".
"She was a fantastic woman; energetic, honest, great fun, she was lovely".
"Jo's killing was created to divide people and promote hatred, we must not let that happen".
She said: "I think what it shows is that people have got a real appetite for something positive to bring people together".
