Convert String to DateTime

import pandas as pd

# Define string
date = '04/03/2021 11:23'

# Convert string to datetime format
date1 = pd.to_datetime(date)

# print to_datetime output
print(date1)

# print day, month and year separately from the to_datetime output
print("Day: ", date1.day)
print("Month", date1.month)
print("Year", date1.year)

convert str to datetime

import datetime

# str value "Apr 2, 2019" convert into any format. 
datetime.datetime.strptime('Apr 2, 2019', '%b %d, %Y').strftime('%a, %d %b %Y')

datetime string to datetime object

// To convert json datetime string to datetime object in c#
// Try this

// For instance if the json string is in this format: "/Date(1409202000000-0500 )/"
// Then wrap it like below

string sa = @"""/Date(1409202000000-0500)/""";

// Create a new instance of datetime object
DateTime dt = new DateTime();

// Deserialize the json string to datetime object
dt = JsonConvert.DeserializeObject<DateTime>(sa);


// Output
// dt = "2014-08-28 3.00.00 PM"
