Build calendars with date and time types

The subject of this tutorial is creating calendars using R. The R language of statistical computing is a free implementation of the S language. This tutorial will show you how to use a Docker image to execute RStudio and how to work with dates and times in R, before explaining how to create calendars – being able to work with dates and times, and knowing how to extract the desired parts from a date string or structure is really important for defining the calendar you want.
