I don't know what the exact odds are but it does happen: My Mum and her older sister are born on the same day 3 years apart, add to the statistical odds of fun I was also born on the same day. Save don't very likely
In my family,my dad,myself and my brother all share the same birthday.(9/11/24; 9/11/52; and 9/11/53). Also,my niece was born on 9/11/85.Three generations! Can anyone beat that?

Odds ratio (AD/BC) is the ratio between number of times that something happens and does not happen. Crude odds ratio is the ratio that is not stratified (ex. by age). Adjusted odds ratio is a stratified odds ratio. If the odds ratio equals one, then there is no association, and null hypothesis shall be accepted. If one is included into confidence interval, then it is possible that odds ratio equals one, and it is not statistically significant. If stratified odds ratios are about the same, or there are no significant differences, the odds ratios are combined into one common odds summary estimate of two stratum specific ORs using Mantel-Haenszel and/or Cohran's tests, or multivariable analysis.
Believe it or not it happens very often for example three generations of women in my family have the same birthday i am the third generation I've seen it a lot more too so the odds are high. I agree, I am born on my mother's birthday and in school I had several friends who were also born on their mother's birthdays.

There are no odds. It just happens.
The fact that twins run in families is actually a myth. The odds of twins having twins is the same as a non-twin having twins. That is about 1 in 33.
About 1 In 1000 Unless you have twins
1/365
I believe the chances of having the same birthday as one of your parents is: 1 out of 183 and the chances of having the same birthday as both parents is: 1 out of 133,225
There is no simple answer since the times of conception may not be independent events.

Odds deal with sets of numbers. You haven't given a group to work with. For example, the odds of two people having the same birthday approaches certainty with a group of thirty or more, but finding someone with your birthday would require 180, just to give a fifty/fifty chance.
