Wednesday
Its in a time of week on a day.
It will fall on them all as the years pass.
i thought it was every 7 years, because there are 7 days in a week
It will fall on every day of the week. because each year, the day of your birthday will increase by one. ex. if my birthday was on a tuesday this year, next year it will be on a wensday. i have no idea how it works but i have experienced everyday of the week on my birthday :)
on what day of the week will my 100th birthday fall?
on what day of the week will my 100th birthday fall?
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.
The simple answer is that their 18th birthday will be on the same day of the week they are born on. What may be the source of your confusion is that most 18th birthdays are on the day of the week after the day of the week of their of birth. The difference here is that 2100 is not a leap year, so there is not that day ahead inserted. Years that are divisible by 100, but not by 400, are not leap years. 2000 was a leap year, but 2100 won't be. Neither was 1900.
Your birthday will fall on a day of the week that depends entirely on what the date of your birth was.
