Find the day you were born
Find your birth weekday
Every calendar date falls on one of seven weekdays. Enter your full birth date and the calculator will tell you whether you were born on a Monday, Tuesday, Wednesday, Thursday, Friday, Saturday or Sunday.
Why your birth weekday is easy to forget
Most people know their birth date, but the weekday rarely comes up after the day itself. The calculator uses the full date, including the year, to find the weekday from the calendar.
Will my birthday be on the same weekday again?
Yes, but not on a fixed seven-year schedule. Normal years shift the weekday by one day. Leap years can shift it by two, depending on where your birthday falls in the year. That means the pattern changes over time.
You can use the birthday calculator to see the weekday of your next birthday instead of working through the cycle yourself.
What about leap-day birthdays?
February 29 exists only in leap years, but the weekday of the actual birth date is still a normal calendar calculation. Enter February 29 and the year you were born to find it.
How far back can I check?
The calculator accepts birth years from 1900 through the current year. That covers living users and most family-history questions people are likely to check here.
