R: Convert to a date

as_date {clock} | R Documentation

## Convert to a date

### Description

`as_date()` is a generic function that converts its input to a date (Date).

There are methods for converting date-times (POSIXct), calendars, time points, and zoned-times to dates.

For converting to a date-time, see `as_date_time()`.

### Usage

    as_date(x)

    ## S3 method for class 'Date'
    as_date(x)

    ## S3 method for class 'POSIXt'
    as_date(x)

    ## S3 method for class 'clock_calendar'
    as_date(x)

    ## S3 method for class 'clock_time_point'
    as_date(x)

    ## S3 method for class 'clock_zoned_time'
    as_date(x)

### Arguments

`x` | `[vector]` A vector.

### Details

Note that clock always assumes that R's Date class is naive, so converting a POSIXct to a Date will always retain the printed year, month, and day value.

This is not a drop-in replacement for `as.Date()`, as it only converts a limited set of types to Date. For parsing characters as dates, see `date_parse()`. For converting numerics to dates, see `vctrs::new_date()` or continue to use `as.Date()`.

### Value

A date with the same length as `x`.

### Examples

    x <- date_time_parse("2019-01-01 23:02:03", "America/New_York")

    # R's `as.Date.POSIXct()` method defaults to changing the printed time
    # to UTC before converting, which can result in odd conversions like this:
    as.Date(x)

    # `as_date()` will never change the printed time before converting
    as_date(x)

    # Can also convert from other clock types
    as_date(year_month_day(2019, 2, 5))
