LandNum

The numerology of birthdays

Is any day of the month luckier for producing famous people? We counted the birthdays of 4,187 notable figures. The most common day to be born is the 8th (162 people); the least common is the 31st (88) — though that partly reflects how often each date occurs in the calendar.

ⓘ How this study was doneLast reviewed June 24, 2026

We took every person in our records with a verified birth date and counted how many were born on each day of the month (1–31), then reduced each day to its birthday number. People with placeholder (January 1) dates are excluded. Note that days 29–31 occur in fewer months, so their totals are naturally lower.
