My original intention in reading this book was to see if it’s straightforward to build a shcal(1) UNIX utility, which would be the Solar Hijri version of cal(1) (link to specs) POSIX-standardized utility. It is 10 days past Nowruz so I can still make it seasonal.
However I found this book itself is very entertaining. It is not aimed at just programmers, it can be used by people of all trades. It has a nice ‘aesthetic’. Like a 13 year old American girl addicted to TikTok would give it a ‘Scholar Core’ label. It is still a reference book, but their reference sections is clean and thorough.
I highly recommend giving it a read. It explains calendars from like a billion years ago. These are truly men of letters writing these, so let’s call it ‘Letters Core’!
I was just commenting on the fact that programming to handle time zone conversions (and daylight savings time) is difficult enough without having to factor planetary orbit into the equation. Colonization aside, even if we found native martians had a calendar they were “currently” using, writing a program to convert from any Earth calendar time to native Martian calendar time would be an astronomical pain in the ass.
Sounds like you might have a lot of hatred in you. I hope you’re going to therapy. I am for that exact reason.
