Common questions

How reliable is a due date worked out by month?

It is an estimate, and births spread across the weeks around it. A conception on day 15 of August gives 8 May, with arrivals spread across the weeks around that date.

Which month will my baby be born?

The due date month is a guide, and many births come earlier or later. A conception in August points to April and May.

What if I only know the month?

Use the middle of the month. The due date then falls in the middle of the window. Day 15 of August maps to 8 May.

How many weeks is the gap?

Divide the days by 7 to get weeks. From day 1 of August to 24 April is 266 days, which is 38 weeks.

What if my cycle is not regular?

When cycles are irregular, an ultrasound can date a pregnancy more reliably than a calendar. A date of 15 August would then give 8 May only as a first guess.
