The estimated date of delivery (EDD), also known as the due date, is the anticipated start date of labor.

Because this is only an estimate, you’ll most likely begin labor two weeks before or after your due date.

In fact, only one in every twenty people gives birth on their expected due date, 

Implying that only 5% of babies are born on their exact calculated due date around the world.

What exactly is the Flo Due Date Calculator, and how does it function?

You can use one of two methods to calculate your due date when using this calculator:

The last menstrual period determines the due date. When using this method, 

280 days is added to the due date to get at the due date.

(or 9 months, the average length of a pregnancy) to the first day of your last menstrual period. 

This assumption is based on a 28-day cycle (cycle lengths can range from 20 to 45 days), 

With menstruation and ovulation occur during the first two weeks of pregnancy. 

Because it is influenced by the regularity of your menstrual cycle, this procedure is not completely reliable.

The due date is determined by the date of conception (or ovulation). 

Using this formula, 266 days of pregnancy are added to the date you conceived.

More Information on Due Date Calculations

  • Method 1: Due date based on last menstrual period

In addition to the standard method used in the Flo calculator, 

There are several other rules for calculating the due date of a pregnancy based on the last menstrual period. 

The rules that follow are modifications to the standard formula to produce more precise results, 

Simply because the more information you can add to the calculation, the more accurate the due date may be.

  1. The Naegele rule

This is the most common method for determining a pregnancy’s due date. 

To calculate the due date, Flo also employs Naegele’s rule as the primary rule.

The conventional formula is as follows:

LMP plus 280 days

This rule considers regular menstruation to be 28 days long 

(it can range from 20 to 45 days), with ovulation occurring on the 14th day of the cycle. 

The estimated due date will be later if your cycle lasts longer. Your due date will be earlier if you have a shorter cycle.

  1. Rule of Mittendorf-Williams

Because the more information you provide, the more accurate the results will be, 

The Mittendorf-Williams rule is considered more advanced than Naegele’s rule.

  • Method 2: Determine the due date using the day of conception.

You’d think that adding 266 days to the date you conceived would give you your due date, but it’s a little more complicated than that. 

Even if you know the exact date of intercourse, you almost never know the precise date of conception. What’s the reason?

Because pinpointing the precise date of ovulation, and thus the date of conception, can be difficult. 

Sperm can survive in the your body for about 5 days, 

While eggs can survive for up to 24 hours after being discharged from the ovary.
