Born in May: When Were You Conceived?

Birthdays & conception. Updated . Calculated with the standard pregnancy dating method used by ACOG and the NHS.

People born in May were most likely conceived between August 8 and September 7 of the year before, assuming they were born close to their due date.

That means most May babies were conceived in the summer (northern hemisphere). Babies born early were conceived a little later than this, and babies born late a little earlier.

For a specific birthday, use the conception calculator by birth date.
