Wondering about trading hours about pandas_market_calendars HOT 3 CLOSED

Are NYSE's and NASDAQ's trading hours the same? Or almost the same? Where would be a better place to ask this?

Yes. All equities exchanges in the US follow the same schedule, and as a tradition the NYSE sets that schedule. You can confirm the holidays for NASDAQ and the market hours here:

https://www.nasdaqtrader.com/Trader.aspx?id=Calendar

Is there any way to know the pre-market and after market hours if you're given the regular trading hours? Is it always a certain numbers of hours before market open and and a certain number of hours after close?

The above link also has information on the extended hours trading for NASDAQ. For NYSE there is info here:

Hi rsheftel,

Thank you for the clear answer on the first point.

Do the pre-market and after-market hours run (are open) if on that day the exchange was closed during regular trading hours?

I dont believe that pre and after hours are open if the market is closed, bit you should check that with the exchange web sites
