What is the best way to calculate due date and estimate delivery date?

It is really complicated. The simple calculations listed below based on a fixed addition from your last menstrual period or those used by most online calculators are terribly inaccurate. A lot of recent research has indicated a number of other variables to consider. (See the page links, further down this page, listed under Related Links).
This is how to calculate your due day. The due month is: your LMP month + 9. The due date is: your LMP date plus 7. For example, if your LMP was 3/10/95: 3 + 9 = 12 (Dec), 10 + 7 = 17 (17th day). If the added month exceeds 12, then you subtract 12. For example, if you LMP was 6/20/95, the month will be (6 + 9) - 12 = 3 (March), and the date will be 20 + 7 = 27, so your due date will be 3/27/96.
- There are loads of methods and calculators out there but their accuracy is limited.
- I was always taught -3 +7, if your LMP was 10/11 you -3m= 7/11 and add 7d= 7/18.
- You can always use an online due date calculator. See the page links, further down this page, listed under Related Links.
- Maybe I don't get it but what is all the maths above? Why would you do all this if someone else would do it for you?
- Due Date Calculation
Pregnancy, on average, lasts 267 days (38 weeks) from conception. If you positively know your conception date, you can add 267 days to it for your due date. The following formulas can also tell your EDD:
Date of the first day of your last period + 281 days = due date
or
Date of the first day of your last period + 7 days - 3 months = due date
The methods here are based on the average 28-day menstrual cycle.

Most midwives and health proffesionals will take the date your last period began and calculate 40 weeks from this giving you a rough due date, this is only providing your last 'period' was actually a period and not spotting if you may have already been pregnant.

∙ 13y agoYour pregnancy due date is calculated from the FIRST day of your last menstrual period. Starting from this day, count 40 weeks forward and that is your due date. This is the typical method used in OB/GYN offices and is the standard way to calculate due date. If the date of you last menstrual period (LMP) is not known, doctors can also estimate a due date based on an ultrasound measurements of the fetus.
