When did you know it was legacy?
My son got me to pick up this game so we could play together in April, so I wasn't around for the move changes or nerfs back in Gen 1. How or when did you know for certain that a move had become legacy? Thanks in advance!

At the top of each page you can click the button that says Pokemon to go to a list of all pokemon or in the search bar type in a specific pokemon's name. On each pokemon's page, its information is listed, including its current and legacy moves and usually rankings for possible movesets.
It is generally a good idea to compare different rankings before making any major decisions for powering up or using TMs. Two other good sources are http://www.pogomoves.com and https://www.pokebattler.com/raids
When there are changes to the moves that are available, they will discussed on this message board and at https://www.reddit.com/r/TheSilphRoad and probably https://www.reddit.com/r/pokemongo and many other sites.
