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
