pandas.Series.tshift

Series.tshift(self, periods=1, freq=None, axis=0) [source]

Shift the time index, using the index’s frequency if available.

Parameters:	periods : int Number of periods to move, can be positive or negative freq : DateOffset, timedelta, or time rule string, default None Increment to use from the tseries module or time rule (e.g. ‘EOM’) axis : int or basestring Corresponds to the axis that contains the Index
Returns:	shifted : Series/DataFrame

Notes

If freq is not specified then tries to use the freq or inferred_freq attributes of the index. If neither of those attributes exist, a ValueError is thrown
