[ygvcvkct] Lived a prime number of days

Count the number of days you have lived and celebrate if it is a prime number.

If the number of days you have lived is divisible by N, then your life at that point may be divided into N equal chapters, and today you are merely beginning chapter N+1. (You can calculate when all the previous chapters were.) But if you have lived a prime number of days, today must be the first day of chapter 2.

This beats (or supplements) celebrating just your birthday, which only occurs once a year. Interestingly, it is possible for your birthday to land on a prime day because of leap years. The number of days you have lived on your birthday might not be a multiple of 365.
