How can I calculate 27 tropical/solar year since my birthdate? Let's say I was born on 27th November 1993 at 03:15:15 AM. Is there any way I can calculate exact 27 tropical cycle since my birthdate/birthtime. 

What date and what time it will be after exact 27 tropical years since my birthdate/birthtime?
From the Wikipedia page on the Tropical year, 


  The mean tropical year is approximately 365 days, 5 hours, 48 minutes, 45 seconds.


Starting from the Tropical year proceeding after your birth date, you can calculate 27 Tropical years forward by adding that approximate amount of time 27 times over.
