Greetings. I was born well after the year -7, so I don't know if there were any calendar shenanigans going on that long ago, but it looks like an error:
greagle@530GA ~/D/p/sbase> ./cal -3 1 -7 January -7 February -7 March -7 Su Mo Tu We Th Fr Sa Su Mo Tu We Th Fr Sa Su Mo Tu We Th Fr Sa 1 2 3 4 5 6 7 1 2 3 4 5 6 1 2 3 4 5 8 9 10 11 12 13 14 7 8 9 10 11 12 13 6 7 8 9 10 11 12 15 16 17 18 19 20 21 14 15 16 17 18 19 20 13 14 15 16 17 18 19 22 23 24 25 26 27 28 21 22 23 24 25 26 27 20 21 22 23 24 25 26 29 30 31 28 27 28 29 30 31 Note that Monday (Feb. 1) follows Tuesday (Jan. 31) and that Tuesday (Mar. 7) follows Sunday (Feb. 28). I cannot compare it to the cal installed on my computer (util-linux) because it only deals with positive years. As I mentioned earlier, I am re-writing cal for my fun and my education, and now it is ready for its debut. I'll introduce it in another message. My re-write does not have this problem. -- http://www.fastmail.com - mmm... Fastmail...
