According to reports from The Athletic’s Shams Charania, the 2020/2021 NBA season is likely to start on December 22.
It is believed that the league office informed its Board of Governors on Friday, October 23, that it intends to schedule the NBA season start three days before Christmas and end in late July 2021.
The NBA is in favor of a play-in tournament for the final playoff seeds, per Charania.

The start date would need to be confirmed by the National Basketball Players Association.
A December 22 start date would allow for the customary October start to the following season.
