Formatting Date and Time VB.NET

The Date literal must be enclosed within number signs (<b>#date#</b>) and specify the date value in the format <b>M/d/yyyy</b> like <b>#09/06/2014#</b>. Else, the way how your code is interpreted may vary depending on the locale in which your application is deployed.<br /> <br /> With this requirement the meaning of your code should never change whether if it has a different date and time format settings. For example, you hard-coded a <b>Date</b> literal of #9/6/2014# which means September 6, 2014. That will compile 9/6/2014 as you want mm/dd/yyyy. However, if you deploy application in several locales using dd/mm/yyyy date format, your hard-coded literal would compile to June 9, 2014. For other locales using yyyy/mm/dd, the literal would be invalid causing compilation error.<br /> <br /> To convert a Date literal to the format of your locale or to a custom format, use the Format function of String class, specifying either a predefined or user-defined date format.<br /> <br /> <h2> Predefined Date/Time Formats</h2> The following table identifies the predefined date and time format names. These may be used by name as the style argument for the Format function: <br /> <table cellpadding="0" cellspacing="0"> <tbody> <tr> <th>Format Name </th> <th>Description </th> </tr> <tr> <td>General Date, or G </td> <td>Displays a date and/or time. For example, <span class="code">3/12/2008 11:07:31 AM. Date display is determined by your application's current culture value.</span> </td> </tr> <tr> <td>Long Date, Medium Date, or D </td> <td>Displays a date according to your current culture's long date format. For example, <span class="code">Wednesday, March 12, 2008.</span> </td> </tr> <tr> <td>Short Date, or d </td> <td>Displays a date using your current culture's short date format. For example, <span class="code">3/12/2008. The d character displays the day in a user-defined date format.</span> </td> </tr> <tr> <td>Long Time, Medium Time, or T </td> <td>Displays a time using your current culture's long time format; typically includes hours, minutes, seconds. For example, <span class="code">11:07:31 AM.</span> </td> </tr> <tr> <td>Short Time or t </td> <td>Displays a time using your current culture's short time format. For example, <span class="code">11:07 AM. The t character displays <span class="code">AM or <span class="code">PM values for locales that use a 12-hour clock in a user-defined time format.</span></span></span> </td> </tr> <tr> <td>f </td> <td>Displays the long date and short time according to your current culture's format. For example, <span class="code">Wednesday, March 12, 2008 11:07 AM.</span> </td> </tr> <tr> <td>F </td> <td>Displays the long date and long time according to your current culture's format. For example, <span class="code">Wednesday, March 12, 2008 11:07:31 AM.</span> </td> </tr> <tr> <td>g </td> <td>Displays the short date and short time according to your current culture's format. For example, <span class="code">3/12/2008 11:07 AM.</span> </td> </tr> <tr> <td>M, <span class="input">m</span> </td> <td>Displays the month and the day of a date. For example, <span class="code">March 12. The M character displays the month in a user-defined date format. The <span class="input">m character displays the minutes in a user-defined time format.</span></span> </td> </tr> <tr> <td>R, <span class="input">r</span> </td> <td>Formats the date according to the <a href="http://msdn.microsoft.com/en-us/library/system.globalization.datetimeformatinfo.rfc1123pattern.aspx"> RFC1123Pattern</a> property. For example, <span class="code">Wed, 12 Mar 2008 11:07:31 GMT. The formatted date does not adjust the value of the date and time. You must adjust the Date/Time value to GMT before calling the <span class="input">Format function.</span></span> </td> </tr> <tr> <td>s </td> <td>Formats the date and time as a sortable index. For example, <span class="code">2008-03-12T11:07:31. The s character displays the seconds in a user-defined time format.</span> </td> </tr> <tr> <td>u </td> <td>Formats the date and time as a GMT sortable index. For example, <span class="code">2008-03-12 11:07:31Z.</span> </td> </tr> <tr> <td>U </td> <td>Formats the date and time with the long date and long time as GMT. For example, <span class="code">Wednesday, March 12, 2008 6:07:31 PM.</span> </td> </tr> <tr> <td>Y, <span class="input">y</span> </td> <td>Formats the date as the year and month. For example, <span class="code">March, 2008. The Y and y characters display the year in a user-defined date format.</span> </td> </tr> </tbody> </table> <br /> <h2> Pre-Defined Format Example</h2> The following example demonstrates how this can be achived. <br /> <pre class="brush: vb"> Public Class Form1 Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load Dim SampleDateTime As Date = #9/6/2014 1:14:23 PM# Debug.Print("Formatting Date and Time Examples:") Debug.Print("Using Format 'D:' " & SampleDateTime.ToString("D")) Debug.Print("Using Format 'd:' " & SampleDateTime.ToString("d")) Debug.Print("Using Format 'T:' " & SampleDateTime.ToString("T")) Debug.Print("Using Format 't:' " & SampleDateTime.ToString("t")) Debug.Print("Using Format 'F:' " & SampleDateTime.ToString("F")) Debug.Print("Using Format 'f:' " & SampleDateTime.ToString("f")) Debug.Print("Using Format 'G:' " & SampleDateTime.ToString("G")) Debug.Print("Using Format 'g:' " & SampleDateTime.ToString("g")) Debug.Print("Using Format 'M:' " & SampleDateTime.ToString("M")) Debug.Print("Using Format 'm:' " & SampleDateTime.ToString("m")) Debug.Print("Using Format 'R:' " & SampleDateTime.ToString("R")) Debug.Print("Using Format 'r:' " & SampleDateTime.ToString("r")) Debug.Print("Using Format 'Y:' " & SampleDateTime.ToString("Y")) Debug.Print("Using Format 'y:' " & SampleDateTime.ToString("y")) End Sub End Class</pre> <br /> <h2> Pre-Defined Output</h2> When the project is compiled it will print the following results. <br /> <pre class="output"> Formatting Date and Time Examples: Using Format 'D:' Saturday, September 06, 2014 Using Format 'd:' 9/6/2014 Using Format 'T:' 1:14:23 PM Using Format 't:' 1:14 PM Using Format 'F:' Saturday, September 06, 2014 1:14:23 PM Using Format 'f:' Saturday, September 06, 2014 1:14 PM Using Format 'G:' 9/6/2014 1:14:23 PM Using Format 'g:' 9/6/2014 1:14 PM Using Format 'M:' September 06 Using Format 'm:' September 06 Using Format 'R:' Sat, 06 Sep 2014 13:14:23 GMT Using Format 'r:' Sat, 06 Sep 2014 13:14:23 GMT Using Format 'Y:' September, 2014 Using Format 'y:' September, 2014</pre> <br /> <h2> User-Defined Date and Time Formats</h2> The following table shows the characters you can use to create user-defined date/time formats. Unlike in earlier versions of Visual Basic, these format characters are case-sensitive. <br /> <table cellpadding="0" cellspacing="0"> <tbody> <tr><th>Character </th> <th>Description </th> </tr> <tr> <td>(:) </td> <td>Time separator. In some locales, other characters may be used to represent the time separator. The time separator separates hours, minutes, and seconds when time values are formatted.

In some locales, other characters may be used to represent the date separator. The date separator separates the day, month, and year when date values are formatted. The actual character that is used as the date separator in formatted output is determined by your application's current culture. </td> </tr> <tr> <td>(%) </td> <td>Used to indicate that the following character should be read as a single-letter format without regard to any trailing letters.
