What Day of the Week Was I Born?
Enter your date of birth to find the weekday you were born, and see which days your birthday will fall on over the next few years.
How the weekday is found
The Gregorian calendar follows a fixed pattern, so every date falls on a weekday that can be calculated exactly. This tool works out that day directly from your date of birth, then lists the weekdays of your upcoming birthdays so you can plan ahead.
Why your birthday moves each year
A common year has 365 days, which is 52 weeks and one day. That is why your birthday usually moves forward by one weekday each year, and by two after a February 29 in a leap year.
When the day gets close, browse birthday wishes by person or turn your message into a personalized card.
