From the Marketplace Datebook, here’s a look at what’s coming up Friday:

• The National Association of Realtors reports on sales of existing homes for January.
• Where are the nation’s governors? They’re headed to Washington for the National Governors Association’s Winter Meeting.
• It’s the anniversary of The New Yorker. The magazine was first published on February 21, 1925
• And on February 21, 1885 the Washington Monument was dedicated in the nation’s capital. There are 897 steps inside. (And an elevator, thank god.)
