Why Does Your Birthday Weekday Change?
A normal year has 365 days, which is one day more than exactly 52 weeks. That usually moves a birthday forward by one weekday the following year. Leap years add an extra day, so the weekday can shift by two depending on where the birthday falls.
This calculator uses the real Gregorian calendar for your date of birth and the next five exact occurrences of that month and day.
