Historic and future holidays, plus bank holidays

[dinakarmu]

Hello, need help with 3 questions:
1.) How historic and future can we go with NYSE calendar?
2.) Will Bank US and Canadian holidays available anytime soon?
3.) Does running pandas_market_calendars needs internet, does it rely on any 3rd party API's? or the calendar derivation is rule based?

1. You can look at the code, I think it goes back to the 1950s or 40s
2. Bank holidays that are NOT stock exchange holidays are not currently implemented. If you want to implement and submit a PR that would be great.
3. Rule based
