The day (calendar) is the default frequency. Parameters ---------- start : str, datetime, date, pandas.Timestamp, or period-like, default None Left bound for generating periods. end : str, datetime, date, pandas.Timestamp, or period-like, default None Right bound for generating periods. periods : int, default None Number of periods to generate. freq : str or DateOffset, optional Frequency alias. By default the freq is taken from `start` or `end` if those are Period objects. Otherwise, the default is ``"D"`` for daily frequency. name : str, default None Name of the resulting PeriodIndex. Returns ------- PeriodIndex Notes ----- Of the three parameters: ``start``, ``end``, and ``periods``, exactly two must be specified. To learn more about the frequency strings, please see `this link `__.
