`month_weekday` represents the nᵗʰ weekday of a month, of an as yet
|
| 21 |
+
unspecified year. To do this the `month_weekday` stores a `month` and a
|
| 22 |
+
`weekday_indexed`.
|
| 23 |
+
|
| 24 |
+
[*Example 1*:
|
| 25 |
+
|
| 26 |
+
``` cpp
|
| 27 |
+
constexpr auto mwd
|
| 28 |
+
= February/Tuesday[3]; // mwd is the third Tuesday of February of an as yet unspecified year
|
| 29 |
+
static_assert(mwd.month() == February);
|
| 30 |
+
static_assert(mwd.weekday_indexed() == Tuesday[3]);
|
| 31 |
+
```
|
| 32 |
+
|

+

`month_weekday` is a trivially copyable and standard-layout class type.

``` cpp

|
| 41 |
+
```
|
| 42 |
+
|
| 43 |
+
*Effects:* Initializes `m_` with `m`, and `wdi_` with `wdi`.
|
| 44 |
+
|
| 45 |
+
``` cpp
|
| 46 |
+
constexpr chrono::month month() const noexcept;
|
| 47 |
+
```
|
| 48 |
+
|
| 49 |
+
*Returns:* `m_`.
|
| 50 |
+
|
| 51 |
+
``` cpp
|
| 52 |
+
constexpr chrono::weekday_indexed weekday_indexed() const noexcept;
|
| 53 |
+
```
|
| 54 |
+
|
| 55 |
+
*Returns:* `wdi_`.
|
| 56 |
+
|
| 57 |
+
``` cpp
|
| 58 |
+
constexpr bool ok() const noexcept;
|
| 59 |
+
```
|
| 60 |
+
|
| 61 |

*Returns:* `m_.ok() && wdi_.ok()`.

``` cpp

|
| 67 |

```
|
| 68 |
+
|
| 69 |

*Returns:*
|
| 70 |

`x.month() == y.month() && x.weekday_indexed() == y.weekday_indexed()`.
|
| 71 |

|
| 72 |

|

```
|

*Effects:* Equivalent to:

``` cpp
