Practical Example

Let’s consider a practical example to illustrate how this tool works:

  • Cycle Length: 30 days
  • First Day of Last Period: November 1, 2025

Calculation:

  • The ovulation day is typically 14 days before the next period. So, the estimated ovulation day would be November 17, 2025.
