pandas.tseries.api.guess_datetime_format

pandas.tseries.api.guess_datetime_format(dt_str, dayfirst=False)

Guess the datetime format of a given datetime string.

Parameters:

dt_str:str

Datetime string to guess the format of.

dayfirst:bool, default False

If True parses dates with the day first, eg 20/01/2005

Warning

dayfirst=True is not strict, but will prefer to parse with day first (this is a known bug).

Returns:

str or None:ret

datetime format string (for strftime or strptime), or None if it can’t be guessed.

Examples

>>> from pandas.tseries.api import guess_datetime_format
>>> guess_datetime_format('09/13/2023')
'%m/%d/%Y'
