Sleep calc

Silly script in Lua to help me with sleep planing. Should work well in termux. Developed with Lua5.3 should work in any Lua5

What it does:

It prints what are the best times to wake up and duration of sleep when presented wake up times are used. Like this:

$ # now it's 01:34; we expect to fall asleep in 5 minutes
$ ./sleepCalc.lua 5
If gonna fall sleep at: 01:39
Wake up | to sleep
------------------
03:04   | 01h30m
04:34   | 03h00m
06:04   | 04h30m
07:34   | 06h00m
09:04   | 07h30m
10:34   | 09h00m
12:04   | 10h30m
13:34   | 12h00m

Usage

• Two (optional) positional arguments

  1. Number of minutes you estimate it will take you to fall asleep

     • Default is 40 because I'm the only expected audience and I always to pray to Luna & Celestia before sleep

  2. How many minutes one sleep cycle takes

     • Default is 90minutes

Notice

• Don't quote me on this I haven't actually done any research in this area
• This is just summarized knowledge I collected from randoms on the internet
• Most of it is probably wrong or oversimplified
• Total amount of research that went into this is < 5
• I just did it a few times and felt it actually worked (could be placebo)

Basic ideas

• Ideal power nap is 20min
• Light sleep part of sleep is every 1h30m
• if you wake up in some multiple of 90 minutes, you should feel fresh a well rested
