LIFESPAN AGE CALCULATOR by Peter Riddell

LIFESPAN Age Calculator is a software date calculator program that can add and subtract dates. Lifespan takes a start date and an end date as input and outputs the elapsed time in years, months and days. Lifespan can also determine a start date if you give it the end date and an elapsed time period in years months and days. Effectively subtracting dates from each other and subtracting ages in years months and days from dates to determine a starting date.

Hi, my name's Peter Riddell, I study IT at CQU and I too have been plagued by the scourge that is date subtraction and spreadsheets, ( I thought they would excel at date subtraction). I then resorted to the internet, downloading a few calculators with their accompanying adware, spyware and nagware. After this painful and fruitless journey I went against my better judgement and decided to solve the problem with my newfound c++ skills. "That should lighten my workload", I thought, "I'll make a tool to do it for me in future". Little did I know the hideous world of exceptions I was to encounter with dastardly date calculations.

Lifespan Age Calculator and Date Calculator is the product of my desire not to have to do any more date calculations than can possibly be avoided. Ironically, in the process of making this, I think I've done more date calculations than Liz Taylor's divorce attorney.

INSTALLATION

Lifespan is a free standing windows program. It is not a file to be opened in another program or an installation program. It does not burn cds, won't make any parts of your body longer and does not wish to send you money from a Kenyan prince. The one file you downloaded is the program. If you've never heard of a zip file just download the unzipped version and you are ready to go. Double click on LIFESPAN.EXE and the program will start to run, follow the prompts and away you go. Check out the animation at the top right of this page to see a detailed step through of Lifespan in action. Copy that file to a floppy or cd and you can take it with you anywhere and run it on any computer without needing to install it. Email it to a friend or colleague but please, at least have them leave a kind word in the message book for me. Have fun!

GUEST BOOK

LINUX and APPLE

LINUX - Lifespan Age Calculator v3.0 will work under the WINE emulator. WINE is installed as a standard part of most modern Linux distros. To run Lifespan Age Calculator in Linux, right click on the Lifespan executable file and choose to "Run In Terminal". If you have a command line fixation, open a terminal, navigate to the folder in which you've stored the single Lifespan executable file and type:
wine lifespan.exe

APPLE - Implementation of the Apple version of Lifespan has proven to be a real pain in the b***. I can only recommend the use of X86 emulation products such as Bosch or PCx. Does anyone know if the Unix back end to OSX has it's own version of WINE? Sorry I can't make if happen for you guys but Lifespan doesn't pay the bills at my place, unfortunately.

NOTE FOR GENEALOGISTS AND HISTORIANS

As you are probably aware, there is a potential 11 day inaccuracy in some dates due to the change-over from the Julian to the Gregorian calenders. Depending upon which country you are dealing with, the 11 days can disappear anywhere from 1582 to 1928. Incorporating this level of detail into Lifespan would destroy it's simplicity. However I am not throwing you to the wolves on this point. This link provides an excellent explanation of this problem and a detailed listing of when many countries made the transition. This transition period is open to conjecture in some countries so some research will be in order. If the Lifespan you are looking at covers the date range relevent to the country you are considering subtract 11 days from the answer Lifespan Age Calculator gives you.
