Hugo's birthday

Hugo was born on a rainy Sunday in Paris in April and turned seven on a sunny Sunday in Tokyo.

How old were you in 1996?

Solution

Birthdays are repeated on the day of the week every six years (there is only one leap in between), but at the end of the century, due to astrophysical correction, despite being leap-days they do not have one more day in February (look at 2000 ). So if Hugo was born in 1896, let's say Sunday, April 5, until 1903 he didn't start cooking his birthday again on Sunday. So in 1996 he turned one hundred years old.
