# 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 | (int, {1, 3,…,27}, default 15) A specific integer for the day of the month.

  See also

  `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')
