Birthdays do not land evenly through the year, and the pattern shifts more than most people expect. In 2025, some months pull ahead while others trail sharply in a way that makes planning everything from parties to staffing feel surprisingly uneven. Let’s look at the Birthdays By Month statistics and see which months are consistently crowded and which ones keep slipping behind.
Key Takeaways
- In the United States for 2022, September had 327,584 births, the highest monthly total, comprising 8.92% of 3,667,758 annual births.
- In Japan 2022, January births were 71,234, lowest monthly at 7.5% of 951,234 total.
- In England and Wales 2022, September births totaled 58,920, highest at 9.1% of 647,889 annual.
- Out of 500 top IMDb actors, 92 born in March (18.4%)
- A 2018 study in Human Reproduction found 6.8% more conceptions in December leading to September births in US.
March has the most birthdays, so it is the busiest month for celebrations.
