1. How to calculate the most accurate due date of a cat
1. The due date of a cat is usually 60-62 days, usually calculated from the day or the next day of the cat\’s breeding. Because cats have different breeds and different physiques, the specific due date of each cat will vary by two or three days, so it cannot be particularly accurate.
2. In addition, some cats may suffer miscarriage or premature birth when they are undernourished or frightened, so it is best to estimate the due date of the cat. At the same time, you should also pay more attention to the cat\’s physical condition. Before giving birth, the cat will have symptoms such as loss of appetite, drop in body temperature, sensitivity and nervousness, rupture of amniotic fluid, and increased vaginal secretions.
2. Calculation formula of expected delivery date
1. If the last menstrual period is clear , the first day of the last menstrual period in the Gregorian calendar is used as the base, the month is subtracted by 3 or added by 9, and the number of days is added by 7. Those who are qualified should check the expected date of delivery based on the early pregnancy ultrasound report;
2. If the last menstrual period is unclear or the pregnancy occurs without menstruation during lactation, ultrasound examination can be used to help estimate the expected date of delivery. At the same time, if the time interval between the gestational age calculated based on the last menstrual period and the gestational age detected by ultrasound is more than 5 days, the expected date of delivery will be corrected based on the early ultrasound examination;
3. Assistance reproductive technology conceived, such as in vitro fertilization, the last menstrual period should be calculated 18 days forward based on the embryo transfer date, and the expected date of delivery should be calculated from this.
3. Baby’s Days of Birth Calculator
Baby’s general health after birth Calculations are based on the lunar calendar. For example, if a child has a hundred days, it will be calculated as 30 days regardless of the age. If the child\’s birthday is on the 10th of February, then the hundred days (years) will be May 20.
4. How to read the concise calculation table of sow due date
1 The concise calculation table of the sow\’s expected delivery date is calculated based on the sow\’s breeding time and the sow\’s average gestation period. Usually the breeding date is used as the starting point, and the expected delivery date is calculated based on the number of days in the gestation period. In the table, the sow\’s breeding date and expected farrowing date are noted, along with the expected number of piglets born. This table is very important for farmers to help them plan and arrange the breeding plan of sows in order to better manage and maintain the production efficiency of the pig farm.
2. At the same time, it can also help breeders prepare necessary equipment and feed in time to ensure the smooth progress of the sow farrowing process.
5. Baby’s birth time calculator

When everything is recorded, you must go to the hospital. The doctor can see the timetable and use the calculator to calculate the time. The test is very important.
6. How to calculate the expected date of delivery if you know the date of intercourse
(1) Calculation based on the date of fetal movement: If you cannot remember the date of your last menstrual period, you can calculate it based on the date of fetal movement. Generally, fetal movements begin between 18 and 20 weeks into pregnancy. The calculation method is: for first-time mothers, the day of fetal movement plus 20 weeks; for multiparous women, the day of fetal movement plus 22 weeks. (2) Calculation based on the basal body temperature curve: The last day of the low temperature segment of the basal body temperature curve is regarded as the ovulation day, and 264-268 days, or 38 weeks, are extrapolated from the ovulation day. (3) Calculation based on B-ultrasound examination: The doctor can estimate the gestational age by measuring the biparietal diameter, crown-rump length and femoral length of the fetal head during B-ultrasound examination, and calculate the expected date of delivery (this method is mostly used by doctors for B-ultrasound examination diagnosis) ). (4)FromEstimation of the start time of morning sickness: Morning sickness usually occurs at the end of the 6th week of pregnancy, which is 42 days after the last menstrual period. From this, the expected date of delivery is calculated backward to 280 days. (5) Approximately estimate the expected date of delivery based on the height of the uterine fundus. If you cannot remember the date of your last menstrual period, you can roughly estimate the expected date of delivery based on the height of the uterine fundus. At the end of the fourth month of pregnancy, the height of the uterus is between the navel and the upper edge of the pubic bone (10 cm above the pubic symphysis); at the end of the fifth month of pregnancy, the fundus of the uterus is 2 fingers below the navel (16-17 cm above the pubic bone); at the end of the sixth month of pregnancy, the fundus of the uterus is level with the belly button (19-20 cm above the pubic bone); at the end of the seventh month of pregnancy, the fundus of the uterus is three fingers above the umbilicus (22-23 cm above the pubic bone); at the end of the eighth month of pregnancy, the xiphoid process of the fundus of the uterus is in the middle of the umbilicus (24-25 above the pubic bone) cm); at the end of the ninth month of pregnancy, the fundus of the uterus is 2 fingers below the xiphoid process (28-30 cm above the pubic bone); at the end of the tenth month of pregnancy, the height of the fundus of the uterus returns to the height at eight months, but the abdominal circumference is lower than at eight months Time is big.
