d = {\'Dates\':[pd.Timestamp(\'2013-01-02\'), pd.Timestamp(\'2013-01-03\'), pd.Timestamp(\'2013-01-04\')], \'Num1\':[1,2,3], \'
I have the same version of pandas, and @DSM's answer was helpful. Another workaround would be to use the apply method:
>>> df.Dates.apply(lambda date: date in [pd.Timestamp('2013-01-04')]) 0 False 1 False 2 True Name: Dates, dtype: bool
