I threw a party to celebrate my 10,000th day of life which happened in 2004 (thats around when you are 27). I am very disappointed I missed my one billionth second of life which happened last year in July (happens when you are 32). Not to miss any of these days here is a script to help calculate them. How long have I lived thus far? Your Date of Birth in following format Day-Month-Year (example: 23-11-1984) :When will I reach this number of days or seconds?
