"Train yourself to let go of everything you fear to lose."
– Yoda
Ever wonder how much time has past and how much you have remaining? This is the tool for you.
Install Babashka don't worry, it's easy.
If you are Borkdude just run it as is.
$ ./lifecalc.clj
Borkdude is 14663 days old, expiration in 14959 days. (50.50% remaining)
Otherwise feed it your information. Lifespan is in years, look yours up here.
$ ./lifecalc.clj --name Hubert --lifespan 75.5 -b 1969-03-26
Hubert is 19000 days old, expiration in 8576 days. (31.10% remaining)
It also suports environment variables in the following format. You can use the export feature to have it generate the variable for you.
$ ./lifecalc.clj --help
-n, --name NAME Name of person
-l, --lifespan YEARS Lifespan in years
-b, --birthday YYYY-MM-DD Birthday
-s, --stdin Read or pipe in from STDIN
-e, --export EXPORT state to bash
-h, --help
$ ./lifecalc.clj --export --name Hubert --lifespan 75.5 -b 1969-03-26
export LIFECALC='{:name "Hubert", :lifespan 75.5, :birthday "1969-03-26"}'
Feed the environment variable (or any combination of environment and command-line) in any way you want.
$ LIFECALC='{:name "Hubert", :lifespan 75.5, :birthday "1969-03-26"}' ./lifecalc.clj
Hubert is 19000 days old, expiration in 8576 days. (31.10% remaining)
$ export LIFECALC='{:name "Hubert", :lifespan 75.5, :birthday "1969-03-26"}'
$ ./lifecalc.clj
Hubert is 19000 days old, expiration in 8576 days. (31.10% remaining)
You can use it like it is for a daily reminder to appreciate life.
Lifecalc will convert a calendar date to your personal day.
$ ./lifecalc.clj 2021-04-01
14662
...and vice-versa
$ ./lifecalc.clj 14662
2021-04-01
Or handily a percentage
$ ./lifecalc.clj 50%
14811
Lifecalc can read from stdin using the -s or -stdin options. So given a file like this
$ cat data-calendar-dates.txt
1969-07-20 moon landing
1981-02-08 Borkdude born
1989-11-09 Berlin Wall is taken down
1992-06-15 US Vice-President Dan Quayle can't spell "potato"
1998-06-01 Digital Equpiment Corporation (DEC) sold and dismantled
2000-01-01 Y2K
2001-11-16 Harry Potter and the Plilosophers Stone film released in theaters
2007-10-16 Clojure release at LispNYC
2008-09-28 SpaceX Falcon 1 launches to orbit
2019-09-19 Babashka initial commit on Github
2021-03-04 ABBA's 50th anniversary of "Waterloo"
You can get the peronal days of every calendar date.
$ ./lifecalc.clj -s < data-calendar-dates.txt
-4221
0
3196
4145
6322
6901

10094

14634
To add more perspecitve, included is a small program interleave-with.clj which interleaves standard-in with a file. Thus you can go full circle complete with explanations.
$ cat data-calendar-dates.txt | ./lifecalc.clj -s | ./interleave-with.clj data-calendar-dates.txt
-4221 1969-07-20 moon landing

The same with day-counts, included as a handy file.
$ cat data-daycounts.txt
1000 first kiloday!
5000 5K-days
10000 10K-days
11000
12000
13000
...
34000
35000 35K-days
35000
36000
36525 100 years old!
$ cat data-daycounts.txt | lifecalc.clj -s | ./interleave-with.clj data-daycounts.txt
1983-11-05 1000 first kiloday!
1994-10-18 5000 5K-days
2008-06-26 10000 10K-days
2011-03-23 11000
2013-12-17 12000
2016-09-12 13000
...
2074-03-12 34000
2076-12-06 35000 35K-days
2076-12-06 35000
2079-09-02 36000
2081-02-08 36525 100 years old!
The same with percentages:
$ cat data-percent.txt
10%
20%
...
120%
125%
$ cat data-percent.txt | ./lifecalc.clj -s
2962
5924
...
35546
37027
Here is a fun trick, remember the converstions convert a percentage to day. Calling it again converts the day to a calendar date.
$ cat data-percent.txt | ./lifecalc.clj -s | ./lifecalc.clj -s
1989-03-20
1997-04-29
...
2078-06-05
2082-06-25
So you can go full circle:
$ cat data-percent.txt | ./lifecalc.clj -s | ./lifecalc.clj -s | ./interleave-with.clj data-percent.txt
1989-03-20 10%
1997-04-29 20%
2001-05-19 25%
2005-06-08 30%
2013-07-18 40%
2021-08-28 50%
2029-10-07 60%
2037-11-16 70%
2045-12-26 80%
2054-02-04 90%
2062-03-17 100%
2070-04-26 110%
2078-06-05 120%
2082-06-25 125%
It looks like Borkdude is going to die on St Patricks day in 2062.
