This EDD calculator is a great due date tool that can determine the estimated moment of birth from the menstrual cycle information. Below the form you can read more on conception and estimated due date in pregnancies.
How does this EDD calculator work?
This useful tool can determine the estimated due date of a pregnancy according to the data of the menstrual cycle (the first day of the last cycle and the length of the cycle).
You will also receive the conception date and the fertile window of that cycle. Beside this info you can also use the EDD calculator to set a desired due date and then figure out when you should conceive in order to give birth to a baby around the desired date.
Example EDD calculation and result:
First part of the form: for a menstrual cycle of 30 days and the start of the latest period being November 15th 2014, the results displayed are:
■ The probable ovulation date is December 2nd, 2014;
■ The possible dates of conception are between November 28th and December 6th, 2014;
■ The estimated due date is August 22nd, 2015.
Second part of the form: the desired due date of October 15th 2015 means:
■ The probable ovulation date is December 2nd, 2014;
■ The possible dates of conception are between November 28th and December 6th, 2014;
■ The estimated due date is August 22nd, 2015;
■ For an estimated due date on October 15th, 2015 the conception should take place on January 22nd, 2015 or at least two days before or after. This is when the ovulation would take place in a menstrual cycle that starts on January 8th, 2015.
