This is a year-month-weekday method for the `calendar_widen()`

generic. It
widens a year-month-weekday vector to the specified `precision`

.

## Usage

```
# S3 method for clock_year_month_weekday
calendar_widen(x, precision)
```

## Arguments

- x
`[clock_year_month_weekday]`

A year-month-weekday vector.

- precision
`[character(1)]`

One of:

`"year"`

`"month"`

`"day"`

`"hour"`

`"minute"`

`"second"`

`"millisecond"`

`"microsecond"`

`"nanosecond"`

## Details

Widening a month precision year-month-weekday to day precision will set
the day and the index to `1`

. This sets the weekday components to the
first Sunday of the month.

## Examples

```
# Month precision
x <- year_month_weekday(2019, 1)
x
#> <year_month_weekday<month>[1]>
#> [1] "2019-01"
# Widen to day precision
# Note that this sets both the day and index to 1,
# i.e. the first Sunday of the month.
calendar_widen(x, "day")
#> <year_month_weekday<day>[1]>
#> [1] "2019-01-Sun[1]"
# Or second precision
sec <- calendar_widen(x, "second")
sec
#> <year_month_weekday<second>[1]>
#> [1] "2019-01-Sun[1]T00:00:00"
```
