Restore those cool hidden macOS calendars

Years ago I wrote about interesting hidden calendars in macOS.

I hadn’t tested this in a long while, until I happened to think of it the other day. In that time Apple had removed the calendars, and thank God too; they saved everyone a whopping 63k.

I found and tested this one liner off StackOverflow to restore the missing calendars.

curl -s https://pkg.freebsd.org/FreeBSD:13:aarch64/latest/All/calendar-data-2022.11.pkg \     | sudo tar xzf - -C / --exclude '*MANIFEST' 

If you followed along with my old post, you’ll need to update the calendar paths to /usr/local/share/calendar/ (instead of /usr/share/calendar/).

While we’re at it, we might as well fix a bug; some of the calendars have overlapping data, hence output can be duplicated.

bash/zsh

_interesting_calendars() {  calendar -A 0 -f /usr/share/calendar/calendar.birthday  calendar -A 0 -f /usr/share/calendar/calendar.computer  calendar -A 0 -f /usr/share/calendar/calendar.history  calendar -A 0 -f /usr/share/calendar/calendar.music  calendar -A 0 -f /usr/share/calendar/calendar.lotr }  today() {  _interesting_calendars|uniq } 

fish

function _interesting_calendars   calendar -A 0 -f /usr/local/share/calendar/calendar.lotr   calendar -A 0 -f /usr/local/share/calendar/calendar.world   calendar -A 0 -f /usr/local/share/calendar/calendar.music   calendar -A 0 -f /usr/local/share/calendar/calendar.computer end  function today   _interesting_calendars|uniq end
