There used to be a long manpage about linux/unix `date` and what dates meant in the past - with examples of 15 century and so. Talking about some king who liked some week/month and decreed it must be repeated, and another who disliked some week and scratched it off the calendar.. It was very eye-opening reading.
But i can not find it anymore. Anyone has an idea ? Is it gone completely?
- Thrymr 2y agoman cal: Two different calendar systems are used, Gregorian and Julian. These are nearly identical systems with Gregorian making a small adjustment to the frequency of leap years; this facilitates improved synchronization with solar events like the equinoxes. The Gregorian calendar reform was introduced in 1582, but its adoption continued up to 1923. By default cal uses the adoption date of 3 Sept 1752. From that date forward the Gregorian calendar is displayed; previous dates use the Julian calendar system. 11 days were removed at the time of adoption to bring the calendar in sync with solar events. So Sept 1752 has a mix of Julian and Gregorian dates by which the 2nd is followed by the 14th (the 3rd through the 13th are absent). https://man7.org/linux/man-pages/man1/cal.1.html https://man7.org/linux/man-pages/man1/cal.1.html
