] ] Does anyone know if there is an on-line resource to know if it's possible to have one year Tuesday November 26h and the following year a Monday August 2nd and what years of late 18th and early 19th centuries could match that criteria?

] In all years (except for leap years) when November 26 is on a Tuesday, August 2 is on a Saturday. In a leap year, it is on a Sunday.

Yes, it seems it cannot be possible, and I've also checked all the years from 1789 to 1813 where there is a August 2nd on Monday(1790, 1802 and 1813), but all the previous years (1789, 1801 and 1812) have November 26th on Thursday, not Tuesday.

BTW, Myretta, thanks for the link on perpetual calendars.

I found another site on perpetual calendars which can give a whole year and holidays on the same page (link below), so I have also noted when was Easter Sunday from 1789 to 1813. Of those 1793, 1796, 1799, 1807 and 1812 had Easter Sunday in late March (an early Easter).
