That's easy: I was being lazy and dumb - I swapped the times instead of converting from UTC to NZDT! I'll leave it like that in the OP as a lesson in when not to be lazy (only particularly eagle eyed monks will notice in any case).

(euro-centric, pre-coffinated me :)

Yeah, Australians have christmas at around the summer solstice and the cold season in July. I must say, spending the christmas holiday on a surfboard instead behind a snow shovel sounds quite nice.

perl -e 'use Crypt::Digest::SHA256 qw[sha256_hex]; print substr(sha256_hex("the Answer To Life, The Universe And Everything"), 6, 2), "\n";'

High time for Austr(al)ian reunification, would also eliminate another linguistic stumble stone ... ;-)

Fun fact: Australia is named after "South" in Latin and Austria after "East" in German (pseudo-latinized) 🤦

...I realized that in the southern hemisphere winter is coming.

It took me a while as well.

Strange how some things we take for granted even though intellectually we know they are not universal. Like March being spring for me at +52.45 degrees latitude!
