Hi,
Because yesterday was unsuitable to check for the ambiguity how the second "1" in that expression is actually parsed. Is it parsed as in:(+1 month 1) thu as in "go next month, its 1st, forward to Thursday", or is it: +1 month (1 thu) as in "go next month (same day as today, i.e. 2nd NOW), forward 1 thu". This would skip the weekdays already passed, such as the upcoming Saturday on Aug 1st. And indeed: $ date -d '+1 month 1 sat' Sat Aug 8 00:00:00 CEST 2020 That is: the expression is, alas, *not* good enough to compute the "first $WEEKDAY of next month". I am at a loss how to do this with NetBSD's date(1).
Thanks for the explanation. Ok, let's try with a double invocation: $ date -d "$(date -d '+1 month' '+%m/01/%C%y') sat" Sat Aug 1 00:00:00 CEST 2020 Ciao, Wolfgang -- wolfg...@solfrank.net Wolfgang Solfrank
