Four months after the delayed conclusion of the 2020 tournament, the 2021 Six Nations will get underway this weekend when Italy take on France on Saturday afternoon.

England will begin their defence campaign when Eddie Jones' men welcome Scotland to Twickenham for the Calcutta Cup clash.

Ireland, who are winless away in Andy Farrell's first year in charge, travel to the Principality Stadium on Sunday to face Wales.

Despite the women's and under-20s competitions being postponed due to the coronavirus pandemic, organisers say the men's tournament will proceed as planned.

It's set to be an explosive return of the famous Rugby Union tournament. Here are the dates for your diary and what channel each fixture is on.

When does the 2021 Six Nations start?

The tournament begins on Saturday 6 February and the final round of games take place on Saturday 20 March, with breaks on the weekends of 20-21 February and 6-7 March.

There are five rounds of fixtures over the six-week period if all goes as planned amid the pandemic, with Six Nations Rugby confirming Covid-19 protocols have been "further reinforced".
