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') FÚnrQécKs`t |||¡t |¡\}}t |d|¡t |d|¡x"|D]}||}t |||¡q>WdS)NÚ_offsetÚ_use_relativedelta)rÚ__init__Ú liboffsetsZ_determine_offsetÚobjectÚ __setattr__)rTr\rQÚkwdsÚoffZuse_rdÚkeyÚvalrErErFr`Òs zDateOffset.__init__cCsÀ|jrt|ƒ}t|jƒdkr®t|ddƒ}|dk rB|jrB|jdd}|jdkrlx>t|jƒD]}||j}qXWn xt|j ƒD]}||j}qzW|dk r¦|jr¦t   ||¡}t |ƒS|t |jƒSdS)NrrH)rH) r_rÚlenrdrMÚreplacer\rr^r rPrGr)rTrUrHÚirErErFÚapplyÜs    zDateOffset.applyc Csdt|ƒtk r tdj|jjdƒ‚|j}ddddddd d h}|jr t|ƒ  |¡r |  dd ¡d |  dd ¡|j }|rœt   |j|¡}t|ƒ||j|jd }|  dd ¡|j }|rì| d¡}t|jtjƒsÐ|j}| |¡}| ¡| d¡}dd„| ¡Dƒ}|rtf|Ž} ||j | }|S|jsDt|dƒrD||j|j St|ƒ|} tdj| dƒ‚dS)a Vectorized apply of DateOffset to DatetimeIndex, raises NotImplentedError for offsets without a vectorized implementation.

Similar to dateutil.rrule except uses pandas DateOffset objects to represent time increments. Parameters ---------- start : datetime (default None) end : datetime (default None) periods : int, (default None) offset : DateOffset, (default BDay()) Notes ----- * This method is faster for generating weekdays than dateutil.rrule * At least two of (start, end, periods) must be specified. * If both start and end are specified, the returned dates will satisfy start <= date <= end.
