The fixtures and schedule for the new Rachael Heyhoe Flint Trophy women's competition have been confirmed by the England and Wales Cricket Board.
The 50-over competition will begin on August, with Finals Day on Saturday, 26 September at a venue to be decided.
It replaces the 20-over Kia Super League, which ran for four years, with Finals Day at Hove.
Eight teams will compete in the Trophy, in two groups of four, compared to only six in the Super League.
Baroness Heyhoe Flint led England to the World Cup in 1973 and is regarded as a trailblazer for women's cricket.
She captained England between 1966 and 1978 and was inducted into the ICC Hall of Fame in 2010. She died in 2017.
"Rachael's determination to give women's cricket the platform it deserves is a legacy that must endure through these difficult times as we continue the journey to professionalise the women's game," said England and Wales chief executive Tom Harrison.
"This summer's tournament will be another important step on that path."
