This app is Life Clock. I made got a hint from the book entitled "3 pm of life"(Japanesse title of Jung’book). I felt like the relationship of that time and age is consistent. The other, it works out in ”What day from birth”, ”What days until the average life”,” How many days until the sixtieth birthday”, “How many days until the next birthday”. Please think carefully look at these numbers. Animals that come out at the birthday at the scene of the clock is the animal of the Japanese zodiac.
