# pandas.tseries.offsets.MonthBegin

class pandas.tseries.offsets.MonthBegin

  DateOffset of one month at beginning.

  MonthBegin goes to the next date which is a start of the month.

  Attributes

  `n` | Return the count of the number of periods.
  `normalize` | Return boolean whether the frequency can align with midnight.

  See also

  `DateOffset`

    Standard kind of date increment.

  Examples

      >>> ts = pd.Timestamp(2022, 11, 30)
      >>> ts + pd.offsets.MonthBegin()
      Timestamp('2022-12-01 00:00:00')

      >>> ts = pd.Timestamp(2022, 12, 1)
      >>> ts + pd.offsets.MonthBegin()
      Timestamp('2023-01-01 00:00:00')

  If you want to get the start of the current month:

      >>> ts = pd.Timestamp(2022, 12, 1)
      >>> pd.offsets.MonthBegin().rollback(ts)
      Timestamp('2022-12-01 00:00:00')
