DateDiff

Calculate the difference between two dates.

That's it! Or is it?

Controls

• A = toggle to/from date
  
• L/R = change day
• B + L/R = change week
  
• U/D = change month
• B + U/D = change year
• MENU = toggle display of years/months/weeks

Limits

• Date calculations are bounded by the 32-bit number limit
• Date range is 2,147,483,647 seconds or about 67 years
• Epoch (oldest year) is by default 1976, the year I was born
• This may be worked around using bignum.lua at some point

You can configure Epoch through Settings file in data folder. The Settings file will only be created when you change menu options.

Shareware

I'm trying something different with this app: it's being distributed as Shareware. This means it's free to download and share with your friends. If you continue to use it you are encouraged to pay what you think it's worth. Basically, it's the honour system. 

Of course, should you wish to pay something at the point of downloading you are quite welcome to do so!
