Overview

Package gregorian provides utility functions for the Gregorian calendar calculations. The Gregorian calendar was officially introduced on 15th October 1582 so, strictly speaking, it only applies after that date. Some countries did not switch to the Gregorian calendar for many years after (such as Great Britain in 1782).

Extending the Gregorian calendar backwards to dates preceding its official introduction produces a proleptic calendar that should be used with some caution for historic dates because it can lead to confusion.
