How old is the Strange Thief Kid, and what is his birthday?

17 years old, a sophomore in high school like Shinichi, June 21.

June 17, June 21.

It's the same day as me, so I remember it super clearly.

February 29th.

There is a month every four years, which means that February 29 is only encountered once every four years. 14 divisible divided by 4 to get 3, so he had three birthdays.

Born on February 29.

Divide the year by 4 (followed by two zeros divided by 400), if the division is a leap year, if it is not divided, it is a common year. For example, 2000 400 = 5 2001 4 = 500 more than 1, so 2000 is a leap year and 2001 is a common year. And so we know that every four years there is a leap year.

The Earth's orbit around the Sun is 365 days, 5 hours, 48 minutes and 46 seconds (conjunction), which is a tropical year. The common year of the Gregorian calendar is only 365 days, which is about a day shorter than the return year, and the remaining time is about one day accumulated over four years, which is added to February in the fourth year, so that the length of the calendar year of that year is 366 days, and this year is a leap year. February in leap years is 29 days.

So I'm 14 years old and I've only had three birthdays.

Now ten-year-old children are on the Internet is really different times, I know that the answer is still here to ask, if it is not a brain teaser it is February 29th, it is not easy, congratulations, two years old.

February 29, of course, because you were born in a leap year.

April 29th.

It is the 119th day of the year in the Gregorian calendar, the 120th day of the leap year, and 246 days before the end of the year, which is World Dance Day and the national holiday of Japan - Showa Day (to commemorate the birthday of Emperor Hirohito).

It's February 29th, is there any other answer??

It should be a leap month, February 28 of the lunar calendar

Your birthday is February 29th, right?

What time is my birthday on July 13th.

February 29 in leap year!

There is a leap in four years, no leap in a hundred years, and another leap in four hundred years.

So 2000 is a leap year, and 2100 is not a leap year.

28 years old!

His grandfather should have been born on February 29. His grandfather should be 60 in a few days. It should be 68 on the 17th birthday.

Grandpa should have been born in a leap year, so a birthday every four years, in his sixties, and 2000 is not a leap year, and he didn't have a birthday, so to be precise, grandpa is 64 years old, his birthday is February 29, and his 17th birthday is 72 years old.

I don't know if it counts when I was born If I count it, plus 4 years old, I hope it will help you Hehe, I space.

It was born on February 29, 1952, and he is 68 years old this year.

Grandpa's birthday is February 29th. The 17th birthday is 2016

Two conditions:

1.Grandpa is very old, and he has only had 14 birthdays before.

2.February 23 is Xiaohong's birthday, and grandpa will be born "in a few days".

It can be deduced that Grandpa's birthday is only once in a few years, and it is very close to February 23. There is only one date, February 29, which is only found in years that are divisible by 4. So grandpa celebrates his birthday once every four years.

In 08, grandpa celebrated his 15th birthday, so 15x4=60, grandpa was born 60 years ago, and he had a one-year-old birthday 56 years ago. 2008-60=1948, grandpa was born in 1948, 60 years old in 08, grandpa's 17th birthday is 2008+4x(17-15)=2016.

February 29, the intercalary month is not intercalary.
