How many days until my birthday? Enter your date of birth below to see a live birthday countdown, your exact age in years, months, and days, and a few fun facts, then get ready to celebrate with our birthday wishes for a friend and other birthday messages.
How the Birthday Countdown Works
Pick your date of birth and tap the button. The calculator instantly shows how many days are left until your next birthday, along with a live countdown in days, hours, minutes, and seconds. It runs entirely in your browser using your device’s clock and time zone, so the countdown hits zero at midnight wherever you are. Your date of birth is never saved or sent anywhere.
Here’s everything you’ll see:
- Your exact age in years, months, and days, plus roughly how many days you’ve been alive.
- Days until your next birthday and the date and weekday it falls on.
- A live countdown that ticks down every second.
- The day of the week you were born, which is a fun fact many people don’t know.
- Your zodiac sign and its date range.
- Your next milestone birthday, such as your 18th, 21st, 30th, 40th, or 50th, with the exact date.
How Old Am I? Birthday Calculator for Your Exact Age
Your age in whole years is easy: it’s how many birthdays you’ve had. Your exact age is a little trickier because months have different lengths. The calculator counts full years since your birth, then the full months since your last birthday, then the remaining days. For example, someone born on March 15, 1990, is 36 years, 7 months, and 30 days old on November 14, 2026.
Turning 21 quotes are a great way to mark one of the biggest milestone birthdays, and the calculator will tell you exactly how many days you have left to plan the party.
What If My Birthday Is on February 29?
Leap-day babies only get a true birthday once every four years. In other years, the calculator shows your birthday on February 28, which is the date most people with a leap-day birthday celebrate (some prefer March 1). You can read more about the calendar behind it in the Wikipedia article on February 29.
Leap year birthday quotes are made for exactly this situation, with funny and sweet lines for anyone who’s technically only had a handful of real birthdays.
Ways to Use Your Birthday Countdown
Plan ahead. Knowing you’re 60 days out gives you time to book a dinner, plan a trip, or save up for something special.
Count down someone else’s birthday. Enter a partner’s, parent’s, or friend’s date of birth to see how many days you have to find the perfect gift and write a card.
Birthday wishes for mom, birthday wishes for your love, and other birthday messages on our site can help you write that card once you know the date.
Share the excitement. Screenshot your countdown and post it in the group chat, or use it to build up to a big milestone like your 30th or 50th.
How to respond to happy birthday is handy once the big day finally arrives and the messages start rolling in.
Zodiac Signs by Birthday
The calculator uses the standard Western zodiac dates: Aries (Mar 21 – Apr 19), Taurus (Apr 20 – May 20), Gemini (May 21 – Jun 20), Cancer (Jun 21 – Jul 22), Leo (Jul 23 – Aug 22), Virgo (Aug 23 – Sep 22), Libra (Sep 23 – Oct 22), Scorpio (Oct 23 – Nov 21), Sagittarius (Nov 22 – Dec 21), Capricorn (Dec 22 – Jan 19), Aquarius (Jan 20 – Feb 18), and Pisces (Feb 19 – Mar 20). If you were born right on the edge of two signs, some astrologers may place you in the neighboring sign depending on the year and time of birth. The Wikipedia page on astrological signs explains how the dates are worked out.
Thank you messages for birthday wishes are the last step of any great birthday, so bookmark them for the day after the party.
