pandas.tseries.offsets.HalfYearBegin

class pandas.tseries.offsets.HalfYearBegin

DateOffset 在每半年的开始日期之间递增。

startingMonth = 1 对应日期如 2007/1/1, 2007/7/1, … startingMonth = 2 对应日期如 2007/2/1, 2007/8/1, … startingMonth = 3 对应日期如 2007/3/1, 2007/9/1, …

属性

n	Return the count of the number of periods.
normalize	Return boolean whether the frequency can align with midnight.
startingMonth	返回半年开始的月份。
