Access last index value of dataframe

The following gives you the last index value:

df.index[-1]

Example:

In [37]:

df.index[-1]
Out[37]:
Timestamp('2015-03-25 00:00:00')

Or you could access the index attribute of the tail:

In [40]:

df.tail(1).index[0]
Out[40]:
Timestamp('2015-03-25 00:00:00')

Old post, but df.last_valid_index() also works.
