Bug#789130: bsdmainutils: [ncal] prints wrong week number
It depends on the current locale and what day, Sunday or Monday, counts as start of the week. In C/POSIX, the first Sunday of the year starts week 1: $ LC_ALL=C ncal -wd 2015-01 January 2015 Su 4 11 18 25 Mo 5 12 19 26 Tu 6 13 20 27 We 7 14 21 28 Th 1 8 15 22 29 Fr 2 9 16 23 30 Sa 3 10 17 24 31 53 1 2 3 4 $ LC_ALL=C ncal -Mwd 2015-01 January 2015 Mo 5 12 19 26 Tu 6 13 20 27 We 7 14 21 28 Th 1 8 15 22 29 Fr 2 9 16 23 30 Sa 3 10 17 24 31 Su 4 11 18 25 1 2 3 4 5 But in de_DE.UTF-8, it's ISO 8601 (i.e. %V): weeks start on a Monday, and week 1 must contain at least four days: $ LC_ALL=de_DE.UTF-8 ncal -wd 2015-01 Januar 2015 Mo 5 12 19 26 Di 6 13 20 27 Mi 7 14 21 28 Do 1 8 15 22 29 Fr 2 9 16 23 30 Sa 3 10 17 24 31 So 4 11 18 25 1 2 3 4 5 $ LC_ALL=de_DE.UTF-8 ncal -wd 2016-01 Januar 2016 Mo 4 11 18 25 Di 5 12 19 26 Mi 6 13 20 27 Do 7 14 21 28 Fr 1 8 15 22 29 Sa 2 9 16 23 30 So 3 10 17 24 31 53 1 2 3 4 $ date -d 2015-01-03 +'%U %V %W' 00 01 00 $ date -d 2015-01-04 +'%U %V %W' 01 01 00 $ date -d 2015-01-05 +'%U %V %W' 01 02 01

Weird. I'd never expect C and C.UTF-8 be different. These are locale values: $ LC_ALL=C locale week-1stweek 4 $ LC_ALL=C.UTF-8 locale week-1stweek 7 $ LC_ALL=en_US locale week-1stweek 7 LC_ALL=en_US.utf8 locale week-1stweek 7 $ LC_ALL=de_DE.utf8 locale week-1stweek 4 $ LC_ALL=ru_RU.utf8 locale week-1stweek 0

Ah, sorry, it seems I was wrong about the C locale. I just cannot make out how it counts weeks. Comments in usr.bin/ncal/calendar.c suggest that it uses ISO definition, except when exactly 3 days of the first week are in the preceding year -- in this case it would use the locale value. Still, I get strange results with en_US.UTF-8, e.g: $ LC_ALL=en_US.UTF-8 ncal -wd 2011-01 January 2011 Su 2 9 16 23 30 Mo 3 10 17 24 31 Tu 4 11 18 25 We 5 12 19 26 Th 6 13 20 27 Fr 7 14 21 28 Sa 1 8 15 22 29 1 2 3 4 5 6
