Birthdays

 Birthdays. 

They mark you gaining another full year of experience. A full rotation around the sun while on our planet. 

The significance of your birthday never goes underappreciated no matter where you are or what you are doing. Whether you are turning 1, turning 13, 16, 18, 21, 25, 50, or 100 and every year in between. Your milestones are your own and you face them and beat them every day.

How you determine your age is slightly more finicky though. Most people start the day you come out of the womb as day 1. Others may consider that same time as day 365 and say you are a year old upon exiting the womb. Neither is really accurate though, is it? They would have to determine your exact conception date to determine how many days old you are. Especially since some babies are born prematurely and others are born late, and then some are formed inside a machine. Of course, there's also the matter of what year you are using as well. I mentioned earlier that it's a full rotation around the sun while on our planet. An Earth year is not the same as a year on any other planet. If you lived on Pluto, you wouldn't even be one yet. None of you would, don't try and fight me on it. Of course that then brings you onto the topic of if time is different there in other ways. Would you still age the same way or would aging be prolonged?
