As of 2015, the Federal Reserve Board of Governors announces the dates and times of their upcoming meetings on their website. The schedule designates which meetings are open to public viewing and attendance, and offers the intended discussion topics for each meeting.
According to federalreserve.gov, meetings are typically held every other Monday and are open to the public unless discussed information involves sensitive or non-public information. The website announces the primary topics for voting and discussion and the members of the board with votes. The site also lists contact information for the Director of the Board Members' Office as a source to direct further questions and information requests.
