The average is once every 7 years. Depending on the occurence of leap years, some days of the week will not have occurred as frequently until a total of 28 years has elapsed.
The day of the week that your birthday falls on changes each year because the 365 calendar days are 1 day more than an even number of weeks. So for NON LEAP YEARS, your next year's birthday will be one day later in the week. Leap years complicate things because they add another day. Birthdays after February 28 are pushed forward 2 days in the week in a Leap Year. Birthdays before February 28 are pushed forward 2 days in the year following a Leap Year. The number of years between your birthday falling on the same day will always be either 5 years, 6 years, or 11 years. (the repeated spacing being 6 years, 11 years, 6 years, 5 years).
**(see related link for any yearly calendar)**
*If you were born in a Leap Year, the exact calendar for that year will only occur every 28th year thereafter.
It will happen most likely 7 years after. I was born on a Sunday, so 7 years later my birthday will fall on a Sunday. Because 7 days in a week! Hope that answers your question!!!
The way to look at this probability is that it is equally likely for your birthday to fall on any given day of the week. There is a 1/7 chance it will land on Saturday. There is a 1/7 chance it will land on Sunday, and so on for all the other days. Taking this into account, it is clear that there is a 1/7 chance of your birthday falling on whatever day you were born.
Thanksgiving always falls on the 4th Thursday in November. Every time the 26th is the 4th Thursday in November, then Thanksgiving and your birthday will fall on the same Thursday.
how often does the same date fall on the same day of the week?
Everyone has a birthday that comes once a year on the same date that they were born.
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.
yes they have the same birthday. they were both born on December 15.
As it is not a birthday, the same date, and it has to fall on a sunday, that is why it never falls on the same day.
i'm gussing same day as L
People born on the same day are commonly referred to as "birthday twins" or simply as "born on the same day."
She was born on the 17th of March 1991.. She has the same birthday as me :D
