When we need to format dates as 1st Jul or 22nd Mar, we can use the following code.

1. DateTime todayDate = DateTime.Now;
2. DateTime dt = DateTime.Parse(todayDate.ToShortDateString(), CultureInfo.GetCultureInfo(“en-US”));  
3. string month = dt.ToString(“MMM”, CultureInfo.GetCultureInfo(“en-US”));  
4.   
5. Calendar calendar = CultureInfo.InvariantCulture.Calendar;  
6.   
7. int dayOfMonth = calendar.GetDayOfMonth(showDate.ShowDate);  
8. string suffix = string.Empty;  
9. string formattedDay;  
10.   
11. switch (dayOfMonth)  
12. {  
13.     case 1:  
14.     case 21:  
15.     case 31: suffix = “st”; break;  
16.     case 2:  
17.     case 22: suffix = “nd”; break;  
18.     case 3:  
19.     case 23: suffix = “rd”; break;  
20.     default: suffix = “th”; break;  
21. } 
22.  
23. formattedDay = dayOfMonth.ToString() + suffix + “ ” + month;

Simple enough, huh? Oh.. one more thing I just wanna jot down. If we need more space for reading or inserting data in MS Office 2007, just hit Ctrl+F1 to hide the Ribbon. The key combination is a toggle key. Hitting them again will bring back Ribbon.
