pandas.tseries.offsets.BusinessDay

class pandas.tseries.offsets.BusinessDay

表示可能 n 个工作日的 DateOffset 子类。

参数:

nint, default 1

表示的天数。

normalizebool，默认为 False

将开始/结束日期规范化为午夜。

offsettimedelta, default timedelta(0)

要应用的日期偏移量。

示例

您可以使用参数 n 来表示 n 个工作日的偏移。

>>> ts = pd.Timestamp(2022, 12, 9, 15)
>>> ts.strftime('%a %d %b %Y %H:%M')
'Fri 09 Dec 2022 15:00'
>>> (ts + pd.offsets.BusinessDay(n=5)).strftime('%a %d %b %Y %H:%M')
'Fri 16 Dec 2022 15:00'

将参数 normalize 设置为 True，可以将下一个工作日的开始时间偏移到午夜。

>>> ts = pd.Timestamp(2022, 12, 9, 15)
>>> ts + pd.offsets.BusinessDay(normalize=True)
Timestamp('2022-12-12 00:00:00')
