About This Data

This page shows the distribution of birthdays from users who have calculated their biorhythm on Biorhyth.me. The data is aggregated and anonymized - only the month and day are analyzed, not the full birth date or any personal information.

Interestingly, birthdays are not evenly distributed throughout the year. September is typically the most common birth month in many countries, while January and February tend to have fewer birthdays. This pattern is often attributed to conception rates during the holiday season.
