Baby Gender Calculator by Lmp

Reviewed by Calculator Editorial Team

Predicting a baby's gender using the last menstrual period (LMP) is a popular but controversial practice. While some believe in the accuracy of gender prediction methods, science shows that gender prediction is not reliable. This calculator provides a fun way to explore the concept while emphasizing the importance of respecting each baby's unique identity.

How the Baby Gender Calculator by LMP Works

The concept of predicting a baby's gender based on the last menstrual period (LMP) dates back to ancient times. The idea is based on the assumption that the sex of a baby can be determined by the day of the week the mother's last menstrual period began.

Gender Prediction Formula

The basic formula for gender prediction is:

Gender = (Day of Week + Number of Weeks Since LMP) mod 2

Where:

  • Day of Week = The day of the week the last menstrual period began (0 for Sunday, 1 for Monday, etc.)
  • Number of Weeks Since LMP = The number of weeks since the last menstrual period began (typically 40 weeks)

This formula is based on the assumption that the sex of a baby is determined by the day of the week the mother's last menstrual period began. However, modern science has shown that this assumption is not accurate.

Example Gender Predictions by LMP
Day of Week Number of Weeks Predicted Gender
Sunday 40 Male
Monday 40 Female
Tuesday 40 Male
Wednesday 40 Female
Thursday 40 Male
Friday 40 Female
Saturday 40 Male
