## Birthday calculator

### Via the birthday calculator

Such a birthday is a nice thing. It comes as sure as the amen in church. Exactly once a year and always on the same day. With the exception of the leap year children, of course, who - at least in theory - can only celebrate once every four years on February 29th.

Our birthday is one of the few things we are pretty sure not to forget. Like someone else's birthday. No need to be ashamed, it happens to the best of us. ;-)

#### What the birthday calculator calculates

For a date of birth, the calculator outputs the current age in years as well as in months, days, hours, minutes and seconds. In addition, the day of the week of the birth, the sign of the zodiac (see chapter Astrology), the duration until the next birthday in months, days, hours and minutes as well as the number of times a birthday took place on the individual days of the week.

In addition, information about the Life Path number, the approximate day of conception, the date of birth in the Julian calendar and the Chinese year of birth are given.

Information on the Egyptian month of birth and the date of birth in the Hebrew calendar are also being planned. The birthday calculator will also display the birthday in the Maya calendar and the Islamic calendar.

Rounded off with the American Zodiac symbol and flower, celebrities who were born on the same day and the birthstone and tree, this birthday calculator should be one of the most comprehensive sources available for general information about a birthday.

#### Leap year

The leap year is an invention to do justice to the fact that a year on earth does not consist of 365 days but actually exactly 365.25 days. The earth needs these 365.25 days to circle the sun once (see heliocentric view of the world in Wikipedia).

In our Gregorian calendar, which only works with "whole" days, quarter days - i.e. the 0.25 of the 365.25 days - cannot be accommodated. Therefore the calendar has to be corrected every four years by adding an extra day in February. The famous February 29th.

The calculation of a leap year is very easy: If the year is divisible by 400, it is always a leap year. Otherwise, the following applies: A leap year is when a year is divisible by 4 but not by 100.

So whose birthday falls on February 29 of a year can actually only celebrate its anniversary properly every four years. In the other three years, a leap year child will have to be limited to February 28th or March 1st.
