When you’re born, you’re not 1. You turn 1 at the end of the year. When you are born, you are 0 years old. Birth marks age, but birth itself can extend between two dates - labour can start on a Monday, but end on a Tuesday. Then there’s also the fact that there’s a common mistake people make - the difference is not the same as counting something.
Let’s say you’ve collected some volumes of a book series. You’ve collected volumes 17 through 21. How many volumes did you collect?
If you do 21-17, you get 4. However, that’s the difference between 21 and 17.
If you list it out and count it, you have FIVE volumes, not four.

It’s really about how you calculate values and mark it. If you are born on Jan 1st, 2010, you don’t turn 1 until you reach Jan 1st, 2011. However, if you’re born in August 1st, 2010, you haven’t turned 1 on Jan 1st, 2011.
so they start at -1?
makes as much sense as taking your birth date as the end of the birth process rather than the start - or even conception.
The end of the birth process rather than the start? What does this mean?
First time mothers can spend more than 24 hours in labor, and the longest ever labor recorded is 75 days.
And do you count the first true contraction as the start? the first signs of dilation? or 6cm dilation? or water breaking?
If the baby doesn’t change much in the last few days or weeks of pregnancy, is it that different from the baby the moment of birth?
for these rare cases id count birth time/date as the time the baby finally became separate. but maybe that’s naive of me…
