I have never used cal or Greg, but it reminds me of the J programming language's calendar function: calendar 2020 //for the full year in one row 3 4 $ calendar 2020 //full year in 4 row/3 column layout You can do all sorts of ranges and views too. Granted it doesn't show the missing days in September 1752 like one poster (petemc_21) replied in this thread, but I keep the J term open on my desktop for all sorts of calculator/programming goodies. Nothing geekier than an ASCII calendar at your fingertips in a full programming terminal!
