Birthday Day Calculator

Calculate which day of the week birthdays occur on, including next birthday, or age range. Wondering which birthdays are on weekends or weekdays? Check your birthday chart!

(Optional) Fill in to calculate for age range

(Optional) Leave empty for You

To generate birthday calendar, enter the person's date of birth. You can chart a specific age, by entering the age in the From Age field. Or, to view an age range, fill in both the From and To age fields. To calculate for age in the current year, leave both fields empty.

The first birthday chart lists each birthday in the specified year range, showing the day of week for each birthday. If you've charted at least two years, a second chart displays the distribution of birthday days over the year range.
