Calendar: iso-year-week-day

Description

iso_year_week_day() constructs a calendar from the ISO year, week number, and week day.

Usage

iso_year_week_day(
  year,
  week = NULL,
  day = NULL,
  hour = NULL,
  minute = NULL,
  second = NULL,
  subsecond = NULL,
  ...,
  subsecond_precision = NULL
)

Arguments

`year`	`⁠[integer]⁠` The ISO year. Values `⁠[-32767, 32767]⁠` are generally allowed.
`week`	`⁠[integer / "last" / NULL]⁠` The ISO week. Values `⁠[1, 53]⁠` are allowed. If `"last"`, then the last week of the ISO year is returned.
`day`	`⁠[integer / NULL]⁠` The day of the week. Values `⁠[1, 7]⁠` are allowed, with 1 = Monday and 7 = Sunday, in accordance with the ISO specifications.
`hour`	`⁠[integer / NULL]⁠` The hour. Values `⁠[0, 23]⁠` are allowed.
`minute`	`⁠[integer / NULL]⁠` The minute. Values `⁠[0, 59]⁠` are allowed.
`second`	`⁠[integer / NULL]⁠` The second. Values `⁠[0, 59]⁠` are allowed.
`subsecond`	`⁠[integer / NULL]⁠` The subsecond. If specified, `subsecond_precision` must also be specified to determine how to interpret the `subsecond`. If using milliseconds, values `⁠[0, 999]⁠` are allowed. If using microseconds, values `⁠[0, 999999]⁠` are allowed. If using nanoseconds, values `⁠[0, 999999999]⁠` are allowed.
`...`	These dots are for future extensions and must be empty.
`subsecond_precision`	`⁠[character(1) / NULL]⁠` The precision to interpret `subsecond` as. One of: `"millisecond"`, `"microsecond"`, or `"nanosecond"`.

Details

Fields are recycled against each other.

Fields are collected in order until the first NULL field is located. No fields after the first NULL field are used.

Value

A iso-year-week-day calendar vector.

Examples

# Year-week
x <- iso_year_week_day(2019:2025, 1)
x

# 2nd day of the first ISO week in multiple years
iso_days <- set_day(x, clock_iso_weekdays$tuesday)
iso_days

# What year-month-day is this?
as_year_month_day(iso_days)
