Arik peace lagos to new york 2018

I think you meant to ask "How long did Ariana Grande's One Love Manchester benefit concert peace tour from Lagos to New York in 2018?"

Ariana Grande's One Love Manchester benefit concert was held on June 4, 2017, at Old Trafford Cricket Ground in Manchester, England, to raise funds for the victims of the Manchester Arena bombing. The concert was a huge success, and it was later followed by a world tour, which included a stop in New York City.

However, I couldn't find any information about a "peace tour" from Lagos to New York in 2018. It's possible that you may be thinking of a different event or concert.

If you could provide more context or clarify what you mean by "peace tour," I'd be happy to try and help you further!
