academiadates

The goal of {academiadates} is to extend {tsibble} by adding a new class which is built to assist handling date intervals that are common in academic institutions, that being three terms annually.

{lubridate} has quarter() and semester() methods to access the quarter or semester from a date. This lacks the functionality for a variable number of periods per year which was proposed in tidyverse/lubridate#1134, but has not received any further work.

{tsibble} has support for quarters in its ecosystem. It also provides scales which wrap ggplot2’s date scales. These can be seen throughout Forecasting: Principles and Practice by Hyndman and Athanasopoulos. The first example of a quarter timescale is in Figure 1.1.
