It is on the family register, and the date of birth is.

The date of birth refers to the day a person was born, which is the date of a person's birth. There are various ways to determine a person's date of birth, such as from a birth certificate, from a hospital record of birth, from a baby registry, etc.

There are generally two types of algorithms for dates of birth, one is based on the calendar and the other is based on historical records. According to the algorithm of the calendar, a person's date of birth can be determined based on the month in which a certain day falls and the day of the month in which it is located; According to the algorithm of historical records, a person's date of birth can be determined based on information such as historical periods, special events, or historical festivals at the time of a person's birth.

The date of birth is very important in people's lives, such as applying for ID cards, opening bank accounts, social security, marriage registration, etc., so it is necessary to pay attention to the date of birth of an individual when determining the date of birth of an individual, and it must be true and reliable to avoid errors.

Calculate how many days there are in the two-day period, divide by 7, and add the remainder to the day of the week at the beginning to get the day of the week. (If the sum is greater than 7, minus 7, it is the number, that is, the day of the week).

For example, if March 1, 2018 is a Thursday, and October 1, 2018 is the day of the week, it is calculated as follows:

The difference is 214 days, 214 7 = 30....4 Thursday + 4-7 = Monday.

October 1, 2018 is Monday.

First of all, add the date number you want to know, add the month code, and divide it by 7, which is divisible by Sunday; If it is not divisible, the remainder is the number, and the day is the day of the week. If the sum of the date and month codes is less than 7, then the sum is the number of days, and that day is the day of the week. For example:

If you want to know what day of the week May 20, 2006 is, add "20" to the code "0" in May 2006, and the sum obtained is 20, and then divide 20 by 7, and the remainder is 6, then May 20, 2006 is week 6. Another example: if you want to know what day of the week February 3, 2006 is, then add "3" to the code "2" for February, and sum it to 5.

Since 5 is less than 7, February 3, 2006 is week 5. Due to the different month codes of each year, the following is given the calculation method of the month codes of each year: First of all, there must be a calendar, and then find a random day, for example, August 5, 2006, that day is the week 6, subtract "5" from "6", and the difference obtained is "1", then the code of August 2006 is 1, and the calculation method of the code of other months can be deduced.

This method is written as a formula: the year and month code, the day of the week of the month, and the date number of the month. Note:

When taking the date number of the month, it must be less than or equal to 7; When taking a Sunday, the value is calculated as 7, and the value of the day of the week of the month is greater than the value of the date number.

The method of calculating the child's date of birth is a false omen: according to the first day of the last menstrual period, it is a total of 280 days of pregnancy, which is the gestational week of ten grandchildren's months, a month is four weeks, and a week is seven days. If menstruation is inaccurate, it can be calculated by the time when fetal movements begin to occur.

The date of birth is the date of birth. In China, there is a lunar calendar and a solar calendar. In some regions, it is customary to use the solar calendar as the date of birth, and in some regions, it is customary to use the lunar calendar.

If it were December 20, 2010 today, it would be the solar calendar. Its corresponding lunar calendar is November 15, 2010.

Calculate how many days are in the two periods, divide by 7, and add the remainder to the day of the week at the beginning to get the day of the week. (If the sum is greater than 7, minus 7, it is the number, that is, the day of the week).

For example, if March 1, 2018 is a Thursday, calculate the day of the week on October 1, 2018

The difference is 214 days, 214 7 = 30....4

Thursday + 4-7 = Monday.

October 1, 2018 is Monday.

Hello dear and happy to answer your <>

Kiss How to calculate which day your birthday is as follows:This, Liang regrets that you should first ask your parents whether it is the lunar calendar or the solar calendar that your parents registered for you. For example, my mom registered me with a lunar birthday.

If Jing Zhengguo is a solar calendar, then you have to ask your parents what day your lunar birthday is, if your parents don't remember your lunar birthday that year, then you can go to the perpetual calendar, what is the corresponding lunar calendar under the solar calendar of the year you were born. Generally speaking, Chinese like to celebrate the lunar birthday, the lunar calendar is fixed, the solar calendar changes, for example, your lunar calendar is August 5, then the lunar calendar August 5 of each year is different, of course, the lunar calendar has 19 years overlapping once a saying, the solar calendar and the lunar calendar of your 19th birthday are the same as the year you were born. 2.

If you want to celebrate the birthday of the solar calendar, according to the Chinese method, the solar calendar of each year is changed according to the lunar calendar, for example, I am the lunar calendar of September 24, I have to check the perpetual calendar every year for my birthday, sometimes in October and sometimes in November. But according to modern calculations, if the solar calendar of the year you were born is August 5th, then the solar calendar may be all passed according to August 5th in the future, because the birthday method of the lunar calendar is too troublesome and has been gradually replaced.
