Birthday Countdown Calculator
How many days until your next birthday? Enter your date of birth for an exact countdown in days, hours, and minutes — plus your zodiac sign, birthstone, and the day of the week you were born.
How the birthday countdown works
The calculator takes your date of birth and finds your next upcoming birthday. If it hasn't happened yet this calendar year, it counts to that date. If it already passed, it counts forward to the same date next year.
The result is broken down into days, hours, and minutes — calculated from the start of today. All processing runs locally in your browser; your date of birth is never sent to any server.
What the calculator shows beyond the countdown
Day of the week your next birthday falls on
Knowing your birthday lands on a Saturday versus a Tuesday matters for planning. The calculator shows this alongside the countdown so you have everything in one place.
Your zodiac sign
Determined by your birth month and day. The 12 signs each cover a specific date range — the calculator identifies yours automatically without a separate lookup.
Your birthstone
Each month has a traditional gemstone associated with it. The calculator shows yours based on your birth month — useful if you've never known which stone is yours.

Each month has a traditional birthstone — January is garnet, June is pearl, October is opal, and so on. Enter your birth date and the calculator shows your stone automatically.
Can I use this to count down to someone else's birthday?
Yes. Just enter their date of birth instead of yours. The calculator doesn't know whose birthday it is — it only needs a date.
What day of the week will my next birthday fall on?

How accurate is the birthday countdown?
The countdown is calculated from the start of the current calendar day. Days are exact. Hours and minutes reflect time elapsed since midnight, not a live ticking clock.
