    calendar_start(x, precision)

    ## S3 method for class 'clock_year_day'
    calendar_end(x, precision)

### Arguments

`x` | `[clock_year_day]` A year-day vector.
`precision` | `[character(1)]` One of: `"year"` `"day"` `"hour"` `"minute"` `"second"` `"millisecond"` `"microsecond"` `"nanosecond"`

### Value

`x` at the same precision, but with some components altered to be at the boundary value.

### Examples

    # Day precision

    x

    # Compute the last day of the year
    calendar_end(x, "year")
