# pandas.tseries.offsets.Day

class pandas.tseries.offsets.Day

  Offset `n` days.

  Represents a calendar-day offset for use in arithmetic with `datetime`, `Timestamp`, or other datetime-like objects. Addition and subtraction shift the value by exactly `n` calendar days, with time-of-day preserved.

  Attributes

  `n` | Return the count of the number of periods.

  See also

  `DateOffset`

    Standard kind of date increment.

  Examples

  You can use the parameter `n` to represent a shift of n days.

      >>> from pandas.tseries.offsets import Day
      >>> ts = pd.Timestamp(2022, 12, 9, 15)
      >>> ts
      Timestamp('2022-12-09 15:00:00')

      >>> ts + Day()
      Timestamp('2022-12-10 15:00:00')
      >>> ts - Day(4)
      Timestamp('2022-12-05 15:00:00')

      >>> ts + Day(-4)
      Timestamp('2022-12-05 15:00:00')

  `freqstr` | Return a string representing the frequency.
  `kwds` | Return a dict of extra parameters for the offset.
  `n` | Return the count of the number of periods.
  `name` | (DEPRECATED) Return a string representing the base frequency.
  `nanos` | Returns an integer of the total number of nanoseconds.
  `normalize` | Return boolean whether the frequency can align with midnight.

  `is_year_end`(ts) | Return boolean whether a timestamp occurs on the year end.
  `is_year_start`(ts) | Return boolean whether a timestamp occurs on the year start.
  `rollback`(dt) | Roll provided date backward to next offset only if not on offset.
  `rollforward`(dt) | Roll provided date forward to next offset only if not on offset.
