dnrdrhc (read it as blood donors check in english, or donor darah cek in Indonesia) is a blood donor reminder which will always reminds you when your blood donor time is coming while you work on the desktop.
In Indonesia, according to Peraturan Menteri Kesehatan 91 tahun 2015, people can donor their blood (Whole Blood) once in 60 days, so this tool uses this rule, although you can change it easily (e.g. if it still use old rule once in 75 days).
dnrdrhc reads database-like txt contains date in Indonesian form which has format:
<donor time> <day> <month> <years>
example:
1 21 September 2015 2 30 November 2015 so on
In this initial release, donor time isn’t useful enough. I just love write it to remind me when I’m not in desktop.
You can edit this database with your favorite editor or echo command.
dnrdrhc will works as your wish with cron (I put example cron command in cron dir that calls this tool every 3 hours in a day).
Please enjoy!
