Create a new date vector or convert a date vector to a new calendar

Description

New dates can be calculated using new_date() for any calendar. Dates can be converted from one calendar to another using as_date(). as_date() also works with the native R Date class and several other classes. When applied to integers, the conversion is from the RD day number (with day 1 being 01-01-01 on the Gregorian calendar).

Usage

as_date(date, calendar)

new_date(..., calendar)

Arguments

date	Date vector on some calendar
calendar	Target calendar of class "calendar"
...	Named arguments denoting the granularities required for calendar.

Value

A date vector of class "rdvec" with the specified calendar.

Examples

april2025 <- new_date(year = 2025, month = 4, day = 1:30, calendar = cal_gregorian)
as_date(april2025, calendar = cal_iso)
