Birthday Weekday Calculator

Free Birthday Weekday Calculator

Use this free birthday weekday calculator to discover which day of the week you were born on, which day your birthday falls on this year and next year, and when it will next land on that same weekday again.

Because a regular year shifts the calendar by one weekday (and a leap year shifts it by two), your birthday moves through the days of the week in a pattern that isn't perfectly predictable year to year, which is part of what makes it fun to track.

Frequently Asked Questions

Why doesn't my birthday fall on the same weekday every year?

A regular 365-day year is exactly 52 weeks plus one extra day, so your birthday shifts forward by one weekday each year. In a leap year, it shifts forward by two weekdays instead, which is why the pattern isn't perfectly regular.

How often does a birthday land on the same weekday as birth?

It varies depending on how many leap years fall in between, but it typically happens every 5 to 6 years, occasionally sooner.

How is the weekend count calculated?

This calculator checks each birthday you've had so far, starting from your first, and counts how many of them fell on a Saturday or Sunday.

Is this calculator free?

Yes, this birthday weekday calculator is completely free to use with no sign-up required.
