Converting dates into a specific format in side a CSV

Question

I am new to python and Iam trying to manipulate some data but it keeps showing me this erro message

 UserWarning: Parsing '13/01/2021' in DD/MM/YYYY format. Provide format or specify infer_datetime_format=True for consistent parsing.
  cache_array = _maybe_cache(arg, format, cache, convert_listlike)

This is my code

import pandas as pd
import matplotlib.pyplot as plt

dataLake = pd.read_csv("datalake - Data lake.csv", parse_dates=["Day"])
dataLake = dataLake.rename(columns={"Day":"day"})
dataLake = dataLake.rename(columns={"Agent":"agent"})

dataLake["day"] = pd.to_datetime(dataLake.day)
print(dataLake.head())
