# usage: just run days-countdown.sh to get a countdown until the default date of October 25
# or specify "from" (e.g. today) and "to" (your target date) in this terrible, terrible format:
# days-countdown.sh "$(gdate)" "$(gdate -d 25-Dec)"
# result is ~/tmp/days-countdown.png
# the png's text color is the hex interpretation of the three-digit days-remaining number ;)
# I use Geektool to position the png on my desktop, and run the script in crontab every hour:
## 44 * * * * /Users/andrewrich/Documents/scripts/days-countdown.sh >/dev/null 2>&1
