The arts events calendar in Tuesday’s issue misstated the time for the Chamber Music Society recital on Monday, Dec. 9. It is at 5 p.m., not 5:30 p.m. (There was also a 7 p.m. Chamber Music Society recital on the same day.)

An article in Tuesday’s issue on third month of paid maternity leave for EECS graduate students provided an incorrect figure for the number of students who have taken advantage of the Physics Department’s third month policy since 2008. The number is three graduate students since 2008, not one or two per year.
