The 2020 NHL Draft date has moved up a few days. The draft will now occur occur on October 6th (1st round) and October 7th (rest of the draft). The draft was originally scheduled for October 9th and 10th. However that was going to conflict with free agency starting the same day.
Believe the 2020 NHL Draft will be moved up to October 6 and 7, from the original tentative dates of October 9 and 10.
Using some educated guess work, I’d guess camps will open on 12/1, which means about 7 weeks of free agency.
