Convert String into a DateTime
string dateInput = "Jan 1, 2009";
var parsedDate = DateTime.Parse(dateInput);
Console.WriteLine(parsedDate);
// Displays the following output on a system whose culture is en-US:
//
1/1/2009 00:00:00
Example of using the DayOfWeek property
https://docs.microsoft.com/en-us/dotnet/api/system.datetime.hour?view=net-6.0
// This example demonstrates the DateTime.DayOfWeek property
using System;
class Sample
{
public static void Main()
{
// Assume the current culture is en-US.
// Create a DateTime for the first of May, 2003.
DateTime dt = new DateTime(2003, 5, 1);
Console.WriteLine("Is Thursday the day of the week for {0:d}?: {1}",
dt, dt.DayOfWeek == DayOfWeek.Thursday);
Console.WriteLine("The day of the week for {0:d} is {1}.", dt, dt.DayOfWeek);
}
}
/*
This example produces the following results:
Is Thursday the day of the week for 5/1/2003?: True
The day of the week for 5/1/2003 is Thursday.

Example of using the Hour property
https://docs.microsoft.com/en-us/dotnet/api/system.eventhandler?view=net-6.0
System.DateTime moment = new System.DateTime(
1999, 1, 13, 3, 57, 32, 11);
// Year gets 1999.
int year = moment.Year;
// Month gets 1 (January).
int month = moment.Month;
// Day gets 13.
int day = moment.Day;
// Hour gets 3.
int hour = moment.Hour;
// Minute gets 57.
int minute = moment.Minute;
// Second gets 32.
int second = moment.Second;
// Millisecond gets 11.
int millisecond = moment.Millisecond;
Example of Using the Minute property
https://docs.microsoft.com/en-us/dotnet/api/system.datetime.minute?view=net-6.0
System.DateTime moment = new System.DateTime(
1999, 1, 13, 3, 57, 32, 11);
// Year gets 1999.
int year = moment.Year;
// Month gets 1 (January).
int month = moment.Month;
// Day gets 13.
int day = moment.Day;
// Hour gets 3.
int hour = moment.Hour;
// Minute gets 57.
int minute = moment.Minute;
// Second gets 32.
int second = moment.Second;
// Millisecond gets 11.
int millisecond = moment.Millisecond;
