Ovulation Due Date Calculator

An Ovulation Due Date Calculator helps estimate your baby’s expected delivery date based on the day you ovulated. This method is highly useful for women who track ovulation rather than relying on their last menstrual period. Since ovulation is when conception typically occurs, this approach can provide a more accurate due date.

Required Input:

  • Ovulation date

Output:

  • Estimated due date
  • Pregnancy timeline (weeks passed and remaining)

Formula:

Due Date = Ovulation Date + 266 days

How to Use the Tool
