`year_month_weekday_last` represents a specific year, month, and last
|
| 32 |
+
weekday of the month. `year_month_weekday_last` is a field-based time
|
| 33 |
+
point with a resolution of `days`, except that it is restricted to
|
| 34 |
+
pointing to the last weekday of a year and month.
|
| 35 |
+
|
| 36 |
+
[*Note 1*: `year_month_weekday_last` supports `years`- and
|
| 37 |
+
`months`-oriented arithmetic, but not `days`-oriented arithmetic. For
|
| 38 |
+
the latter, there is a conversion to `sys_days`, which efficiently
|
| 39 |
+
supports `days`-oriented arithmetic. — *end note*]
|
| 40 |
+
|
| 41 |
+
`year_month_weekday_last` meets the *Cpp17EqualityComparable* (
|
| 42 |
+
[[cpp17.equalitycomparable]]) requirements.
|
| 43 |
+
|
| 44 |
+
`year_month_weekday_last` is a trivially copyable and standard-layout
|
| 45 |
+
class type.
