Family birthdays share same numbers

As of the 23rd May 2022 this website is archived and will receive no further updates.

understandinguncertainty.org was produced by the Winton programme for the public understanding of risk based in the Statistical Laboratory in the University of Cambridge. The aim was to help improve the way that uncertainty and risk are discussed in society, and show how probability and statistics can be both useful and entertaining.

Many of the animations were produced using Flash and will no longer work.

In my family, we share the same numbers for birthdays and are always in 3s. Different years and sometimes different months but always the same number and always in sets of 3. (no twins in my family and no planning) 3 people born on 13th- Jan, July, Dec 3 on 29th- Aug, Sept 3 on 22nd- Jan, May 3 on 21st- Sept, May, June? I believe there are other dates but those are the ones I remember.
