pandas.Timestamp.floor

Timestamp.floor(self, freq, ambiguous='raise', nonexistent='raise')

return a new Timestamp floored to this resolution

Parameters:

freq : a freq string indicating the flooring resolution ambiguous : bool, ‘NaT’, default ‘raise’ 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 : ‘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.

Raises:

ValueError if the freq cannot be converted
