Conception Date Calculator
  • This conception date calculator tells you when you have conceived and also gives you the due date as to when you can expect your baby.
  • Conception occurs fourteen days before your period is due. If you have a twenty eight day menstrual cycle you will ovulate on day 14. If your cycle is a few days longer, you probably ovulated after day fourteen, and your baby may arrive a few days after your estimated due date.
  • The due date is calculated by adding 40 weeks to the date of conception.
