Conceived on Juneteenth? Here's the Due Date

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

If conception happened on Juneteenth (June 19), the baby would be due around March 12 the following year.

Remember that sex and conception aren't always on the same day: sperm can survive for up to five days, so a holiday celebration could lead to conception a few days later.
