35 weeks and 5 days is how many months?

In medical terms, 35 weeks and 5 days is recorded as gestational week 35+5. Generally speaking, gestational week 35+5 is more than eight months but less than nine months. The detailed explanation is as follows:

Currently, prenatal checkups calculate gestational age based on the first day of the last menstrual period, with each seven-day interval counting as one week, for a total of 40 weeks. The 40th week marks the estimated due date. Since one week consists of seven days, 35 weeks equals 7 × 35 = 245 days; adding another 5 days gives a total of 250 days. Months vary in length: large months in the Gregorian calendar have 31 days, small months have 30 days (February has 28 days in a common year and 29 days in a leap year). Dividing 250 by 30 gives a quotient of 8 and a remainder of 10, indicating that 35 weeks and 5 days corresponds to more than eight months but not yet nine months. However, gestational age should be confirmed based on ultrasound findings rather than relying solely on the last menstrual period, as individual menstrual cycles vary. Therefore, when confirming gestational age, a discrepancy of up to about one week is generally considered acceptable. Moreover, the estimated due date does not necessarily indicate the exact date of delivery.

Gestational week 35+5 falls within the third trimester. As labor could begin at any time, it's important to get adequate rest, avoid strenuous physical activity, and尽量避免独处，以防分娩突然发生而无法及时就医。
