How many years until my birthday is on the same day?

To determine how many years until your birthday falls on the same day of the week, you'll need to know which day of the week your birthday currently lands on and the year. Generally, a birthday will repeat on the same day of the week every 6, 5, or 11 years, depending on leap years. You can calculate the specific number of years by checking a calendar or using a date calculator for your birth date and the upcoming years.
