Checking on Date and Time (C#)


Is it Mother Date and Father Time? Any way, getting all the different date and time displays working can be imperturbably perplexing at times. You take a look at it in this Windows Console Application.

code snippet
// retrieve and format date/time data
// tested with VCS.NET 2003

using System;  // has all the date/time stuff
class myApp
  public static void Main()
    DateTime CurrTime = DateTime.Now;
    Console.WriteLine("DateTime display listing specifier and result:\n");

    Console.WriteLine("d = {0:d}", CurrTime );  // Short date mm/dd/yyyy
    Console.WriteLine("D = {0:D}", CurrTime );  // Long date day, month dd, yyyy
    Console.WriteLine("f = {0:f}", CurrTime );  // Full date/short time day, month dd, yyyy hh:mm
    Console.WriteLine("F = {0:F}", CurrTime );  // Full date/full time day, month dd, yyyy HH:mm:ss AM/PM
    Console.WriteLine("g = {0:g}", CurrTime );  // Short date/short time mm/dd/yyyy HH:mm
    Console.WriteLine("G = {0:G}", CurrTime );  // Short date/long time mm/dd/yyyy hh:mm:ss
    Console.WriteLine("M = {0:M}", CurrTime );  // Month dd
    Console.WriteLine("R = {0:R}", CurrTime );  // ddd Month yyyy hh:mm:ss GMT
    Console.WriteLine("s = {0:s}", CurrTime );  // yyyy-mm-dd hh:mm:ss  can be sorted!
    Console.WriteLine("t = {0:t}", CurrTime );  // Short time hh:mm AM/PM
    Console.WriteLine("T = {0:T}", CurrTime );  // Long time hh:mm:ss AM/PM
    Console.WriteLine("u = {0:u}", CurrTime );  // yyyy-mm-dd hh:mm:ss  universal/sortable
    Console.WriteLine("U = {0:U}", CurrTime );  // day, month dd, yyyy hh:mm:ss AM/PM
    Console.WriteLine("Y = {0:Y}", CurrTime );  // Month, yyyy
    Console.WriteLine("DateTime.Month     = " + CurrTime.Month);      // number of month
    Console.WriteLine("DateTime.DayOfWeek = " + CurrTime.DayOfWeek);  // full name of day
    Console.WriteLine("DateTime.TimeOfDay = " + CurrTime.TimeOfDay);  // 24 hour time
    // number of 100-nanosecond intervals that have elapsed since 1/1/0001, 12:00am
    // useful for time-elapsed measurements
    Console.WriteLine("DateTime.Ticks     = " + CurrTime.Ticks);

    Console.Read();  // wait

It should be also mentioned that you can combine these as in DateTime.Now.ToString("dd/MM/yyyy h:MM tt") - for 13/12/2007 5:04 PM as an example


May I know how to make the following comparison:

A(Date/Time) + B(Integer, in HOUR) <= C.

if after A+B is next day of the date A then is should be increase one day then only compare with C.

How can I make it !!

Thanks in advance

If Iwant Do that in Windows Form
DateTime CurrTime = DateTime.Now;

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

//Farhan program for date validation

namespace ConsoleApplication2
    class Program
        static void Main(string[] args)

            string date =

Suppose i want to write the code which will tell/great the user according to time e.g Goodmorning, goodvening e.t.c. How may i write this code.

You can convert DateTime value to an integer, to get the hour and minutes seperated values. And then use them to compare to the hours which defines to when you say good morning and afternoon.

DateTime time = DateTime.Now;
            int hour = time.Hour;
            int minutes=time.Minute;
            if (hour <= 12)
                Console.WriteLine("Good morning");
            else if (hour >= 12 && minutes >= 1)
                Console.WriteLine("Good afternoon");

Hope it helps,
