Syntax
public sealed class LocalDatePattern : IPattern<LocalDate>Properties
FullRoundtrip
Gets an invariant local date pattern which round trips values including the calendar system.
This corresponds to the text pattern "uuuu'-'MM'-'dd '('c')'".
Since 3.0.x
Availability net6.0, net8.0, netstandard2.0
Declaration
public static LocalDatePattern FullRoundtrip { get; }Property Value
| Type | Description |
|---|---|
| LocalDatePattern | An invariant local date pattern which round trips values including the calendar system. |
Remarks
This pattern corresponds to the 'r' standard pattern.
Iso
Gets an invariant local date pattern which is ISO-8601 compatible and which round trips values, but doesn't include the calendar system.
This corresponds to the text pattern "uuuu'-'MM'-'dd".
Since 1.4.x
Availability net6.0, net8.0, netstandard2.0
Declaration
public static LocalDatePattern Iso { get; }Property Value
| Type | Description |
|---|---|
| LocalDatePattern | An invariant local date pattern which is ISO-8601 compatible. |
Remarks
This pattern corresponds to the 'R' standard pattern.
PatternText
Gets the pattern text for this pattern, as supplied on creation.
Since 1.0.x
Availability net6.0, net8.0, netstandard2.0
Declaration
public string PatternText { get; }Property Value
| Type | Description |
|---|---|
| string | The pattern text for this pattern, as supplied on creation. |
TemplateValue
Gets the value used as a template for parsing: any field values unspecified
in the pattern are taken from the template.
Since 1.0.x
Availability net6.0, net8.0, netstandard2.0
Declaration
public LocalDate TemplateValue { get; }Property Value
| Type | Description |
|---|---|
| LocalDate | The value used as a template for parsing. |
TwoDigitYearMax
Maximum two-digit-year in the template to treat as the current century.
If the value parsed is higher than this, the result is adjusted to the previous century.
This value defaults to 30. To create a pattern with a different value, use WithTwoDigitYearMax(int).

Declaration
public int TwoDigitYearMax { get; }Property Value
| Type | Description |
|---|---|

Remarks
See the user guide for the available pattern text options. Note that the current culture
is captured at the time this method is called - it is not captured at the point of parsing
or formatting values.
Exceptions

|---|---|
| InvalidPatternException | The pattern text was invalid. |
CreateWithInvariantCulture(string)
Creates a pattern for the given pattern text in the invariant culture.

Declaration
public string Format(LocalDate value)Parameters
| Type | Name | Description |

Returns
| Type | Description |
|---|---|

Remarks
This method never throws an exception (barring a bug in Noda Time itself). Even errors such as
the argument being null are wrapped in a parse result.
WithCalendar(CalendarSystem)
Creates a pattern like this one, but with the template value modified to use
the specified calendar system.
Since 2.0.x
Availability net6.0, net8.0, netstandard2.0
Declaration
public LocalDatePattern WithCalendar(CalendarSystem calendar)Parameters

Returns
| Type | Description |
|---|---|
| LocalDatePattern | A new pattern with a template value in the specified calendar system. |
Remarks
Care should be taken in two (relatively rare) scenarios. Although the default template value is supported by all Noda Time calendar systems, if a pattern is created with a different template value and then this method is called with a calendar system which doesn't support that date, an exception will be thrown. Additionally, if the pattern only specifies some date fields, it's possible that the new template value will not be suitable for all values.

culture.
