pandas.Timestamp.round

Timestamp.round(freq, ambiguous='raise', nonexistent='raise')

Round the Timestamp to the specified resolution.

Parameters
freqstr

Frequency string indicating the rounding resolution.

ambiguousbool or {‘raise’, ‘NaT’}, default ‘raise’

The behavior is as follows:

  • bool contains flags to determine if time is dst or not (note that this flag is only applicable for ambiguous fall dst dates).

  • ‘NaT’ will return NaT for an ambiguous time.

  • ‘raise’ will raise an AmbiguousTimeError for an ambiguous time.

New in version 0.24.0.

nonexistent{‘raise’, ‘shift_forward’, ‘shift_backward, ‘NaT’, timedelta}, default ‘raise’

A nonexistent time does not exist in a particular timezone where clocks moved forward due to DST.

  • ‘shift_forward’ will shift the nonexistent time forward to the closest existing time.

  • ‘shift_backward’ will shift the nonexistent time backward to the closest existing time.

  • ‘NaT’ will return NaT where there are nonexistent times.

  • timedelta objects will shift nonexistent times by the timedelta.

  • ‘raise’ will raise an NonExistentTimeError if there are nonexistent times.

New in version 0.24.0.

Returns
a new Timestamp rounded to the given resolution of freq
Raises
ValueError if the freq cannot be converted
