How old would someone be if they were born on the 30th october 1992?

Today is March, 19th 2016

so from 1992 have been: 2016 - 1992 = 24 years

but the date is from October 30th, so we are not at 24 years just yet, we are at 23 years and the months and days since last 30th October, that is:

November + December + January + February = 4 months

and some days more, 19 days because today is 19th, so the total is:

23 years, 4 months, 19 days

Simple its 2016 and they are born on 1992 so 2016-1992 = 24. but there birthday is in October so they will be 23
