pandas.tseries.offsets.SemiMonthBegin

class pandas.tseries.offsets.SemiMonthBegin

Two DateOffset’s per month repeating on the first day of the month & day_of_month.

This offset moves dates to the first day of the month and an additional specified day (typically the 15th by default), useful in scenarios where bi-monthly processing occurs on set days.

Attributes

n	Return the count of the number of periods.
normalize	Return boolean whether the frequency can align with midnight.
day_of_month	Return the day of the month for the semi-monthly offset.

tseries.offsets.SemiMonthEnd

Two DateOffset’s per month repeating on the last day of the month & day_of_month.

tseries.offsets.MonthEnd

Offset to the last calendar day of the month.

tseries.offsets.MonthBegin

Offset to the first calendar day of the month.

Examples

>>> ts = pd.Timestamp(2022, 1, 1)
>>> ts + pd.offsets.SemiMonthBegin()
Timestamp('2022-01-15 00:00:00')
