What Day of the Week Was I Born?
The weekday of any date, plus day of the year, week number and whether it was a leap year.
The weekday of a birth date is fixed by the Gregorian calendar, and because an ordinary year advances the weekday by one day and a leap year by two, a birthday moves forward one or two weekdays each year.
