Important Eras in the Japanese calendars are based on the emperor's reign and are therefore expected to change. The following examples use the Parse and Parse Exact methods to parse a string and convert it to a Date Time value. Write Line(date ISO8602) var date String = "5/1/2008 AM"; Date Time date1 = Date Time. Internally, all Date Time values are represented as the number of ticks (the number of 100-nanosecond intervals) that have elapsed since midnight, January 1, 0001.

The following code snippets show examples of each: You call any of the overloads of the Date Time constructor that specify elements of the date and time value (such as the year, month, and day, or the number of ticks). Invariant Culture)) ' The following method call displays True. Typically, date and time strings have two different usages in applications: You use the Parse or Try Parse method to convert a string from one of the common date and time formats used by a culture to a Date Time value. Write Line("Strings that could not be parsed: ") For Each bad Format In bad Formats Console. To persist a Date Time value as an integer: The following example persists an array of Date Time values as integers on a system in the U. // // When restored on an en-GB system, the example displays the following output: // Current Time Zone: (UTC) Dublin, Edinburgh, Lisbon, London // The dates on an en-GB system: // 14 June 2014 // 11 July 2014 // 10 January 2015 // 21 December 2014 // 02 June 2014 // Restored dates... public static void Persist As XML() // The example displays the following output: // Leap year days from 2000-2100 on an en-GB system: // 29/02/2000 29/02/2004 29/02/2008 29/02/2012 29/02/2016 // 29/02/2020 29/02/2024 29/02/2028 29/02/2032 29/02/2036 // 29/02/2040 29/02/2044 29/02/2048 29/02/2052 29/02/2056 // 29/02/2060 29/02/2064 29/02/2068 29/02/2072 29/02/2076 // 29/02/2080 29/02/2084 29/02/2088 29/02/2092 29/02/2096 Public Sub Persist As Xml() ' Serialize the data. Date Time values may also reflect moments in time in a time zone other than local and UTC.The following code creates a specific date using the Date Time constructor specifying the year, month, day, hour, minute, and second. (For details on the implicit parameterless constructor of a value type, see Value Types.) Some compilers also support declaring a Date Time value without explicitly assigning a value to it. The following example shows how you can use Try Parse to convert date strings in different culture-specific formats to a Date Time value. Write Line($" ") Next End If ' The example displays the following output: ' Date String Date ' ' 01/06/2013 01/06/2013 ' 01/06/13 01/06/2013 ' 1/6/13 01/06/2013 ' 1.6.13 01/06/2013 ' 2013-06-01 01/06/2013 ' 01 June 2013 01/06/2013 ' 1 June 2013 01/06/2013 ' 01 June 2013 01/06/2013 ' 01 June 2013 01/06/2013 ' 01 June 2013 PM 01/06/2013 ' 01 June 2013 PM 01/06/2013 ' 1 June 2013 01/06/2013 ' 1 June 2013 01/06/2013 ' 1 June 2013 PM 01/06/2013 ' 1 June 2013 PM 01/06/2013 ' 01 June 2013 01/06/2013 ' 01 June 2013 01/06/2013 ' 01 June 2013 PM 01/06/2013 ' 01 June 2013 PM 01/06/2013 ' 1 June 2013 01/06/2013 ' 1 June 2013 01/06/2013 ' 1 June 2013 PM 01/06/2013 ' 1 June 2013 PM 01/06/2013 ' 01/06/2013 01/06/2013 ' 01/06/2013 01/06/2013 ' 01/06/2013 PM 01/06/2013 ' 01/06/2013 PM 01/06/2013 ' 01/06/13 01/06/2013 ' 01/06/13 01/06/2013 ' 01/06/13 PM 01/06/2013 ' 01/06/13 PM 01/06/2013 ' 1/6/13 01/06/2013 ' 1/6/13 01/06/2013 ' 1/6/13 PM 01/06/2013 ' 1/6/13 PM 01/06/2013 ' 1.6.13 01/06/2013 ' 1.6.13 01/06/2013 ' 1.6.13 PM 01/06/2013 ' 1.6.13 PM 01/06/2013 ' 2013-06-01 01/06/2013 ' 2013-06-01 01/06/2013 ' 2013-06-01 PM 01/06/2013 ' 2013-06-01 PM 01/06/2013 ' 01/06/2013 01/06/2013 ' 01/06/2013 01/06/2013 ' 01/06/2013 PM 01/06/2013 ' 01/06/2013 PM 01/06/2013 ' 01/06/13 01/06/2013 ' 01/06/13 01/06/2013 ' 01/06/13 PM 01/06/2013 ' 01/06/13 PM 01/06/2013 ' 1/6/13 01/06/2013 ' 1/6/13 01/06/2013 ' 1/6/13 PM 01/06/2013 ' 1/6/13 PM 01/06/2013 ' 1.6.13 01/06/2013 ' 1.6.13 01/06/2013 ' 1.6.13 PM 01/06/2013 ' 1.6.13 PM 01/06/2013 ' 2013-06-01 01/06/2013 ' 2013-06-01 01/06/2013 ' 2013-06-01 PM 01/06/2013 ' 2013-06-01 PM 01/06/2013 ' 01 June 01/06/2013 ' 01 June 01/06/2013 ' 2013-06-01T.0000000 01/06/2013 ' 2013-06-01T.0000000 01/06/2013 ' Sat, GMT 01/06/2013 ' Sat, GMT 01/06/2013 ' 2013-06-01T 01/06/2013 ' 22/04/2013 ' 22/04/2013 ' PM 22/04/2013 ' PM 22/04/2013 ' 22/04/2013 ' 22/04/2013 ' PM 22/04/2013 ' PM 22/04/2013 ' 2013-06-01 Z 01/06/2013 ' 01 June 2013 01/06/2013 ' 01 June 2013 01/06/2013 ' 01 June 2013 PM 01/06/2013 ' 01 June 2013 PM 01/06/2013 ' 1 June 2013 01/06/2013 ' 1 June 2013 01/06/2013 ' 1 June 2013 PM 01/06/2013 ' 1 June 2013 PM 01/06/2013 ' June 2013 01/06/2013 ' June 2013 01/06/2013 You use the Parse Exact and Try Parse Exact methods to convert a string that must match a particular format or formats to a Date Time value.

Because the Date Time structure is not time zone-aware, you have to serialize both the Date Time value and the Time Zone Info object that represents its time zone.Creating a value without an explicit initialization also results in the default value. It changes the current culture to English (Great Britain) and calls the Get Date Time Formats() method to generate an array of date and time strings.

When it comes to determining if a year is a leap year, since AD 8 the Julian calendar has always had 48 months between two leap days.
