Frequently asked questions

How accurate is the due date?

The due date is an estimate. Only about 4% of babies are born exactly on it; most arrive between weeks 38 and 42. A first-trimester ultrasound gives the most accurate date.

When should we start choosing a name?

Many parents start in the second trimester, and many learn the baby's sex around week 20. Starting early leaves time to build a shortlist, try the full name with your surname and ask family for their opinion.

What if we can't agree on a name?

Each of you can save favourite names, then create a shared list and vote. A name duel helps you pick one favourite out of several, and the Name DNA test shows which style you both like.

When does the name need to be registered?

It depends on the country — usually within a few days to a few weeks after birth. Check your local registry office's rules in advance, as some countries restrict which names can be given.

The calculator gives an estimate only and is not medical advice. Your doctor or midwife will confirm the due date.
