Rcalendar

A simple $R$ package containing a lookup table between different ways of expressing dates for the years between 1970 and 2025.

You don't actually need $R$ installed, as you can just download the calendar.csv file from the data-raw/csv sub folder.

In the same folder you can also find the following tables:

• uk_holidays with the British Bank holidays
• seasons with the starting days of the astronomical seasons (thanks to Jay Tanner)
• metadata with the description of all the columns in the other datasets
