Property Value

The string designator for hours that are "post meridiem" (after noon). The default for InvariantInfo is "PM".

Exception typeCondition


The property is being set to a null reference (Nothing in Visual Basic).


The property is being set and the DateTimeFormatInfo is read-only.

If the custom pattern includes the format pattern "tt" and the time is after noon, DateTime.ToString displays the value of PMDesignator in place of the "tt" in the format pattern. If the custom pattern includes the format pattern "t", only the first character of PMDesignator is displayed. Your application should use "tt" for languages for which it is necessary to maintain the distinction between AM and PM. An example is Japanese, for which the AM and PM designators differ in the second character instead of the first character.

For cultures that do not use a PM designator, this property returns an empty string.
