calendar_leap_year {clock} | R Documentation

## Is the calendar year a leap year?

### Description

`calendar_leap_year()` detects if the year is a leap year according to the Gregorian calendar. It is only relevant for calendar types that use a Gregorian year, i.e. `year_month_day()`, `year_month_weekday()`, and `year_day()`.

### Usage

    calendar_leap_year(x)

### Arguments

`x` | `[calendar]` A calendar type to detect leap years in.

### Value

A logical vector the same size as `x`. Returns `TRUE` if in a leap year, `FALSE` if not in a leap year, and `NA` if `x` is `NA`.

### Examples

    x <- year_month_day(c(2019:2024, NA))
    calendar_leap_year(x)
