The weekday-drift problem, solved 📅

Most people know their birthday's date instantly but not its weekday this year — because it moves. Every ordinary year pushes your birthday one weekday forward (365 mod 7 = 1); leap years push it two (366 mod 7 = 2), when the extra day falls before your date. Over an 11-year span your birthday touches at least 8 different weekdays. This tool does the modular arithmetic so you don't have to.

What the calendar card shows 🗓️

The full month of your next birthday, correctly laid out (first weekday, month length, leap February).
Your birthday cell in pink with a 🎂, today outlined in blue.
Exact date, weekday, age turning, days remaining, and the zodiac sign of that date.

The .ics export — how it works 📤

Clicking export builds a standard iCalendar file (RFC 5545) entirely in your browser: a whole-day event on your birthday, titled with the age you're turning. It imports cleanly into Google Calendar, Apple Calendar, Outlook and any calendar that speaks .ics. No account, no upload — the file is generated and downloaded locally.

Planning around the date 🎉

Weekend birthdays are party gold; weekday birthdays deserve an office cake at minimum. If your next one lands mid-week, our party planning guide has the weekend-shift strategy, and the Birthday Countdown keeps the hype ticking live. For the rare golden one where age matches date, see the Golden Birthday Calculator.

📆 FAQ

When is my next birthday?

Enter your date of birth — you'll get the exact date, weekday and age you're turning, rendered on a calendar of that month.

Can I add it to my calendar app?

Yes — the export button downloads a standard .ics file that works with Google, Apple and Outlook calendars.

What about February 29 birthdays?

In non-leap years the finder targets February 28; in leap years it lands on the true date.

Is my birth date stored?

No — everything runs in your browser; nothing is uploaded, saved or tracked.

Why do birthdays drift across weekdays?

Normal years shift one weekday, leap years two — your birthday rotates through the week over time.

Yes — the .ics export button downloads a calendar file that imports into Google, Apple and Outlook calendars.

What makes certain birthdays special?

The finder flags milestone ages (1, 5, 10, 13, 16, 18, 21, 30…) with a fun fact for each, so you know which birthdays deserve extra cake.
