Windows date and time format

One of the best things is that Windows provides extensive customization options to modify the date and time formats. No matter the reason, if you ever want to change the date or time format in Windows 11, follow the steps given below.

It will be done in no time. You can only select from the pre-defined formats. If you want to set a custom format, follow the third section. You can only select from pre-defined formats. Kind property in text. The formatted string can be parsed back by using the DateTime. ParseExact method if the styles parameter is set to DateTimeStyles. In this string, the pairs of single quotation marks that delimit individual characters, such as the hyphens, the colons, and the letter "T", indicate that the individual character is a literal that cannot be changed.

The apostrophes do not appear in the output string. The time zone component of DateTimeKind. All DateTimeOffset values are also represented in this format. Utc date and time values uses "Z" which stands for zero offset to represent UTC. Unspecified date and time values have no time zone information. Because the "O" or "o" standard format specifier conforms to an international standard, the formatting or parsing operation that uses the specifier always uses the invariant culture and the Gregorian calendar.

In the case of DateTime objects, the parsing overload that you call should also include a styles parameter with a value of DateTimeStyles. Note that if you call a parsing method with the custom format string that corresponds to the "O" or "o" format specifier, you won't get the same results as "O" or "o". This is because parsing methods that use a custom format string can't parse the string representation of date and time values that lack a time zone component or use "Z" to indicate UTC.

The following example uses the "o" format specifier to display a series of DateTime values and a DateTimeOffset value on a system in the U. Pacific Time zone. The following example uses the "o" format specifier to create a formatted string, and then restores the original date and time value by calling a date and time Parse method.

The "R" or "r" standard format specifier represents a custom date and time format string that is defined by the DateTimeFormatInfo. RFCPattern property. The pattern reflects a defined standard, and the property is read-only. Therefore, it is always the same, regardless of the culture used or the format provider supplied. When this standard format specifier is used, the formatting or parsing operation always uses the invariant culture.

InvariantInfo property that represents the invariant culture. ToUniversalTime method before you perform the formatting operation. In contrast, DateTimeOffset values perform this conversion automatically; there is no need to call the DateTimeOffset. ToUniversalTime method before the formatting operation. The following example uses the "r" format specifier to display a DateTime and a DateTimeOffset value on a system in the U.

The "s" standard format specifier represents a custom date and time format string that is defined by the DateTimeFormatInfo. SortableDateTimePattern property. The pattern reflects a defined standard ISO , and the property is read-only. The purpose of the "s" format specifier is to produce result strings that sort consistently in ascending or descending order based on date and time values.

As a result, although the "s" standard format specifier represents a date and time value in a consistent format, the formatting operation does not modify the value of the date and time object that is being formatted to reflect its DateTime.

Kind property or its DateTimeOffset. Offset value. The following example uses the "s" format specifier to display a DateTime and a DateTimeOffset value on a system in the U. The "u" standard format specifier represents a custom date and time format string that is defined by the DateTimeFormatInfo.

UniversalSortableDateTimePattern property. Although the result string should express a time as Coordinated Universal Time UTC , no conversion of the original DateTime value is performed during the formatting operation.

ToUniversalTime method before formatting it. The "U" standard format specifier represents a custom date and time format string that is defined by a specified culture's DateTimeFormatInfo. The pattern is the same as the "F" pattern. The "t" standard format specifier represents a custom date and time format string that is defined by the current DateTimeFormatInfo. ShortTimePattern property. For example, the custom format string for the invariant culture is "HH:mm".

ShortTimePattern property of some cultures may not make use of all properties. The "T" standard format specifier represents a custom date and time format string that is defined by a specific culture's DateTimeFormatInfo. LongTimePattern property. For example, the custom format string for the invariant culture is "HH:mm:ss". LongTimePattern property of some cultures may not make use of all properties.

The "M" or "m" standard format specifier represents a custom date and time format string that is defined by the current DateTimeFormatInfo. MonthDayPattern property. For example, the custom format string for the invariant culture is "MMMM dd". The "Y" or "y" standard format specifier represents a custom date and time format string that is defined by the DateTimeFormatInfo.

YearMonthPattern property of a specified culture. Tip : You can also close the Customize Format window, and then change date and time formats at one time in the Region window, as shown in the following picture.
