Fleniny Calendar

I need a simple DATE type calculator. There will be 2 dates: BIRTHDAY DATE and NAME DAY DATE I need a application which will calculate the exact day (if 2, i need the one closer to BIRTHDAY DATE) between these two dates in the bigger "break". Expample: BIRTHDAY DATE: MARCH 10 NAME DAY DATE: JUN 10 DAYS between: MARCH 10 to JUNE 10 is = 91 DAYS between: JUNE 10 and MARCH 10 is= 272 Now we need to use the bigger "break" which is 272. 272/2=136 (if the number is .5, we have EXACT MIDDLE) Now we have 2 dates in the exact middle 136th and 137th. I need the one closer to the BIRTHDAY DATE which is 137th from JUNE 10th and that's: 25th of Ocotber. That's the DATE I need!!! i don't really care for the FEBRUARY. It could 28days at all times. I need it as web application for my webesite. Now I use DATE CALCULATOR (in tow steps) from DAVID LEITHOUSER [login to view URL] or web app: [login to view URL]~des/datecalc/[login to view URL]
