Does the date of birth change everyone's birthday? Whether it's the solar calendar, the new calendar or the lunar calendar.

Since it is a birthday, it is unique and will not change;

However, some people have a special date of birth and will have a birthday when they grow up. If they are strict, they will not be able to live.

For example, there are the following special cases:

Born on February 29th in the leap year of the Gregorian calendar, which occurs once every four years;

Born in the leap month of the lunar calendar, it appears once every n years (the emergence cycle is not fixed, there are long and short);

Born on the last day of the lunar calendar, it appears once every n years (the emergence cycle is not fixed, there are long and short);

But in any case, according to the solar calendar can reduce uncertainty, which is also its universal practicability;

Gregorian birthdays (except February 29th) are the same every year, which is easy to remember.

Lunar calendar (essentially lunar calendar), that is, lunar calendar, old calendar, yellow calendar, China traditional calendar.

Gregorian calendar, namely solar calendar, new calendar, national calendar and international calendar.
