People with birthdays on February 29.

February 29 is a very special day, a day that humans make up every four years in order to make up for the little extra 365 days in a year.

The Earth's orbital cycle 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 has only 365 days, which is about one day shorter than the return year, and it accumulates about one day every four years, adding this day to the end of February (i.e., February 29).

The current method of intercalation in the Gregorian calendar is as follows: one leap every four years, but no intercalation in every 100 years, such as 2100 and 2200. However, every 400 years need to have another leap day, for example, 2000 and 2400 are leap years.

So what is the birthday once in 4 years? What is a birthday in four years?

In fact, the birthday that only happens once in four years is February 29th.

Although birthdays only occur once every four years, the number of years that should be increased has not had a special impact on people's age.

No. It is not possible to have two birthdays in a year, we often use the lunar calendar commemoration method and the solar calendar chronology, and these two times will rarely overlap together, so it will lead to a solar birthday and a lunar birthday in a year, and in numerology and feng shui, it is okay to go to the birthday of Yuan Jueliang, but it is not possible to go to two birthdays in a year, otherwise it will have a negative impact on your own fortune and bring damage to your lifespan.

Reasons for lunar birthdays:

Lunar birthday is more auspicious, lunar birthday is a traditional custom, many people will think that the day of birth in the lunar calendar is more accurate, although the solar calendar is relatively fixed, but the lunar calendar is not able to correspond, and some areas think that the solar birthday is better, it is very easy to remember, so people will think that their solar birthday is better, and they will not let themselves forget.

Birthday is the best on the same day, such as macro fiber fruit in advance, about seven days is the best, can not exceed seven days, otherwise there is no meaning to celebrate the birthday, birthday is a more important moment for people, children are more looking forward to their birthday, is to hope that their birthday can come early, but adults are more disgusted. <>

Yes, for example, those born on February 29 in leap years. For example, if you were born in 1896, there is a leap in 4 years, no leap in 100 years, and then in 400 years, so 1900 is not a leap year, there is no birthday, and you must not have a birthday until 1904.

If the person was born on February 29, 1896, then his "one-year-old" birthday was on February 29, 1904.

That is, there is no February 29 in the year when the number of years can be divided by 100 but not by 400.
