A global, 16-team women's rugby competition was launched on Tuesday in an effort to unify the calendar across the hemispheres and raise competitiveness in the 15-a-side game.
The competition, called WXV, is set to begin in 2023 and will consist of three tiers. It will be staged from September to October each year, except in Rugby World Cup years.
The 2021 Women's Rugby World Cup in New Zealand was pushed back until 2022 last week because of the pandemic.
World Rugby chairman Bill Beaumont said the establishment of a global women's calendar was a "landmark moment for the sport."
"This is an ambitious, long-term commitment to make the global game more competitive, to grow the women's game and support the expansion of Rugby World Cup to 16 teams from 2025 and beyond," Beaumont said.
