The story of the Time Addition Calculator
Those of you who know me know I hacked a lot of BASIC on my Commodore 64 in the 80s, but when I went to college, I became an artist and performer, got a Mac, and stopped programming. I only picked it back up a dozen-plus years later in my 30s because I needed tools or had creative ideas that needed code to implement. I couldn’t afford to pay someone else, so I just picked up the coding knowledge to DIY.
The other day, I found myself wanting to add up a list of times. A quick Googling/Binging for “time calculator” mostly turned up tools that would give you the difference between two dates in seconds, or give you the Unix timestamp for any date/time. I just wanted a simple calculator where I could use my keypad to enter in times in a simple format, and tally them up.
I know I could do it in Excel, but I wanted to simply enter them very quickly on the numeric keypad, using dots instead of colons.
So I built one and put it on GitHub with an MIT License: https://github.com/YiddishNinja/LittleTools
Give it a try…
