LIFESPAN AGE CALCULATOR can subtract dates answering in days months and years elapsed. Can also subtract an age from an end date to caclulate a start date.. Very useful for government forms in my country, thats for sure.

ELAPSED TIME CALCULATION
eg: DD/MM/YYYY -- DD/MM/YYYY == X days Y months Z years

START DATE CALCULATION
eg: DD/MM/YYYY -- X days Y months Z years == DD/MM/YYYY

A tiny footprint (35k zipped, 80k unzipped) makes Lifespan Age Calculator very easy to email to a friend and easy on your computer too ;) Did I mention it's a free way for home users to subtract dates? I hope you like it.
kind regards,
