How to estimate Expected Date of Delivery by Quickening?

Quickening is also known as a feeling of life. It refers to the feeling of active fetal movements for the first time by the mother in utero.

It is usually felt at the 18th week in mothers with first pregnancy (primigravida) and at the 16th week in mothers with subsequent pregnancies (multigravida). In some cases, it can be felt as early as 12 weeks and delayed up to 28 weeks (especially in obese women). A feeling of fetal movements signifies the wellbeing of the baby during pregnancy.

It is a useful guide to calculate the expected date of delivery. If you know your last menstrual period then it becomes easier to calculate the expected date of delivery.

To calculate the expected date of delivery (EDD) by quickening, you need to know about the weeks of your pregnancy and the time (week) at which you felt the first baby movements then only you can calculate the EDD.

The duration of a pregnancy is about 40 weeks or 9 months and 7 days from the first day of your last menstrual period.

If you would like to know the expected date of delivery by quickening then you should know the exact week when you felt the baby move for the first time. Suppose you felt your baby’s movement at the 18th week then subtract it from 40 weeks and you will get the expected date of delivery.

40 weeks - 18 weeks = 22 weeks

It means it will take 22 weeks for you to give birth to your baby.

Let’s take another example- You felt your first baby movements at 24th week then

40 weeks - 24 weeks = 16 weeks are remaining for your delivery.

In the beginning, you may feel fewer movements but as the pregnancy progresses the movements become more. If you don’t feel any baby movements till 24 weeks of pregnancy then you need to consult your doctor.


In the above post, we discussed the method to calculate the expected date of delivery by quickening.

Thank you all!!! Hope you find this useful.
