Roster

I know they are updated during the season, but I was wondering how often they are updated, every week or when there is a player transfer or substitution.

During the season, its usually close to a weekly roster update. However. That may very depending on player movement. So to be on the safe side. Say every one to two weeks.

Thank you very much for the information.

I would like to ask what or what website is used to create the roster for the NHL?

While we don't guarantee there's going to be a roster update every 2 weeks, that's normally about when they're released. You can look at the previous updates to see how often they come out.
