Traditionally, the Women's Six Nations Championship is run concurrently with the men's tournament.

However, in January 2021, the 2021 Women's Six Nations Championship was postponed due to the COVID-19 pandemic,[2] which caused travel and time restrictions issues due to qualification of the 2021 Rugby World Cup needing to be completed before the tournament starts in September.

This, combined with national lockdowns and the need for COVID-19 testing, made it more difficult to schedule the matches during the pandemic.
