Hello ... consult: ... if I buy the New York Pass for 3 days, can I use two days of Big Bus from different circuits?

They are as you say, three days and you can take what you have hired wherever you want to go. Check it out

Thank you. It is good data to rener present. At first I thought I could do all of them. Good clarification

It is only one day. That day you can take the buses you want but the next day you do not enter the Pass anymore
