Works exactly like relativedelta in terms of the keyword args you pass in, use of the keyword n is discouraged-- you would be better off specifying n in the keywords you use, but regardless it is there for you. n is needed for DateOffset subclasses. DateOffets work as follows. Each offset specify a set of dates that conform to the DateOffset. For example, Bday defines this set to be the set of dates that are weekdays (M-F). To test if a date is in the set of a DateOffset dateOffset we can use the onOffset method: dateOffset.onOffset(date). If a date is not on a valid date, the rollback and rollforward methods can be used to roll the date to the nearest valid date before/after the date. DateOffsets can be created to move dates forward a given number of valid dates. For example, Bday(2) can be added to a date to move it two business days forward. If the date does not start on a valid date, first it is moved to a valid date. Thus pseudo code is: def __add__(date): date = rollback(date) # does nothing if date is valid return date + When a date offset is created for a negative number of periods, the date is first rolled forward. The pseudo code is: def __add__(date): date = rollforward(date) # does nothing is date is valid return date + Zero presents a problem. Should it roll forward or back? We arbitrarily have it rollforward: date + BDay(0) == BDay.rollforward(date) Since 0 is a bit weird, we suggest avoiding its use. Parameters ---------- n : int, default 1 The number of time periods the offset represents. normalize : bool, default False Whether to round the result of a DateOffset addition down to the previous midnight. **kwds Temporal parameter that add to or replace the offset value. Parameters that **add** to the offset (like Timedelta): - years - months - weeks - days - hours - minutes - seconds - microseconds - nanoseconds Parameters that **replace** the offset value: - year - month - day - weekday - hour - minute - second - microsecond - nanosecond See Also -------- dateutil.relativedelta.relativedelta Examples -------- >>> ts = pd.Timestamp('2017-01-01 09:10:11') >>> ts + DateOffset(months=3) Timestamp('2017-04-01 09:10:11') >>> ts = pd.Timestamp('2017-01-01 09:10:11') >>> ts + DateOffset(month=3) Timestamp('2017-03-01 09:10:11') tnRNicKstj|||tj|\}}tj|d|tj|d|x+|D]#}||}tj|||qUWdS(Nt_offsett_use_relativedelta(Rt__init__t liboffsetst_determine_offsettobjectt __setattr__(RSR\RNtkwdstofftuse_rdtkeytval((s5lib/python2.7/site-packages/pandas/tseries/offsets.pyR_s  cCs|jrt|}nt|jdkrt|dd}|dk ri|jri|jdd}n|jdkrxOt|jD]}||j }qWn(x%t|j D]}||j }qW|dk r|jrt j ||}nt |S|t |jSdS(NiRD(R^RtlenRdRIRJtreplaceR\RR]R RMRCR(RSRTRDti((s5lib/python2.7/site-packages/pandas/tseries/offsets.pytapplys  c Cst|tk r3tdjd|jjn|j}ddddddd d h}|jrt|j |r|j dd d |j dd |j }|rt j |j|}t||d |jd|j}n|j dd |j }|ra|jd}t|jtjs6|j}n|j|}|j|jd}nd|jD}|rt|} ||j | }n|S|j rt|dr||j|j St||} tdjd| dS(s Vectorized apply of DateOffset to DatetimeIndex, raises NotImplentedError for offsets without a vectorized implementation.
