class pandas.tseries.offsets.BQuarterBegin#
DateOffset increments between the first business day of each Quarter.
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.

| is_quarter_start(ts) | Return boolean whether a timestamp occurs on the quarter start. |
| is_year_end(ts) | Return boolean whether a timestamp occurs on the year end. |
| is_year_start(ts) | Return boolean whether a timestamp occurs on the year start. |
| rollback(dt) | Roll provided date backward to next offset only if not on offset. |
