pandas.tseries.offsets.QuarterBegin — pandas 2.2.3 documentation (original) (raw)
class pandas.tseries.offsets.QuarterBegin#
DateOffset increments between Quarter start dates.
startingMonth = 1 corresponds to dates like 1/01/2007, 4/01/2007, … startingMonth = 2 corresponds to dates like 2/01/2007, 5/01/2007, … startingMonth = 3 corresponds to dates like 3/01/2007, 6/01/2007, …
Parameters:
nint, default 1
The number of quarters represented.
normalizebool, default False
Normalize start/end dates to midnight before generating date range.
startingMonthint, default 3
A specific integer for the month of the year from which we start quarters.
