Hi Jenny, I made the decision to do 1800 to 1899. The purists say 1801 to 1900 is correct. However, I celebrated the milennium on Dec. 31, 1999 - Jan. 1, 2000 along with folks all over the world. Not much happened the next year.

For 19th century, what do you enter? 1800 to 1899 1801 to 1900 1800 to 1900 Interested to hear your thoughts, Jenny Wilker Avanti!
