Enter your birth date (month, day, year). 2. Click Calculate. 3. Review weekday born, star sign, Chinese zodiac, birthstone, next birthday date, and how long you have lived. For full age in years and months on any date, use the [Age Calculator](https://shoutingnow.com/tools/age-calculator/). To compare two birthdays, try the [Age Difference Calculator](https://shoutingnow.com/tools/age-difference-calculator/). ## What does this birthday calculator show? People look up more than just their age when they type in a birth date. This tool pulls together the calendar facts people ask about most: - Weekday born: Monday, Tuesday, etc. - Star sign: Western zodiac sun sign from your birth month and day - Chinese zodiac: animal sign from your birth year - Birthstone: traditional stone for your birth month - Next birthday: date and days remaining - Time lived: months, weeks, and days so far ### Leap-day birthdays Born on 29 February? In years without a leap day, the countdown to your next birthday uses 28 February instead, since the 29th simply does not exist that year. It is the standard way to handle leap-day birthdays. ### Star sign vs Chinese zodiac A Western star sign comes from where your birth month and day fall in the solar year. The Chinese zodiac runs on the lunar calendar instead, and the animal typically flips over in late January or February. This calculator sticks with birth year for the animal sign, the same shortcut most quick-reference tools use. ## Examples and use cases ### Worked example Birth date **15 July 1995** (a Saturday): - Star sign: Cancer (June 21 to July 22) - Chinese zodiac: Pig (1995) - Birthstone: Ruby ### Real-world use cases - Party planning: Someone checks how many days until a milestone birthday to send invitations and book a venue. - Genealogy curiosity: A family historian notes the weekday and zodiac for each ancestor’s birth date in a shared tree. - Gift ideas: A friend looks up birthstone and star sign before choosing jewelry or a themed birthday card. ### Related tools - Age Calculator: exact age on any date - Generations Calculator: cohort by birth year - Age Difference Calculator: gap between two people ## Frequently Asked Questions ### What does the birthday calculator show? The day of the week you were born, your Western star sign, Chinese zodiac animal, birthstone, days remaining until your next birthday, and how long you have been alive in months, weeks, and days. ### How is the next birthday countdown calculated? It looks for the next calendar date carrying your birth month and day on or after today, then counts the days between. If you were born on a leap day, it falls back to 28 February in years without one. ### How is my star sign determined? Western sun signs come from your birth month and day matched against the standard zodiac date ranges, right on the [Birthday Calculator](https://shoutingnow.com/tools/birthday-calculator/). ### How is Chinese zodiac calculated? Your animal sign follows the common 12-year cycle tied to birth year (Rat, Ox, Tiger, and so on). This quick-reference tool does not apply Lunar New Year date boundaries. ### What is a birthstone? A gem traditionally tied to your birth month, garnet for January or sapphire for September, for example. The calculator lists the stone along with a short description. ### Can I get my exact age here too? This page sticks to birthday facts and the countdown. For your full age on any date, head to the [Age Calculator](https://shoutingnow.com/tools/age-calculator/), and for generational labels, try the [Generations Calculator](https://shoutingnow.com/tools/generations-calculator/). ```json [{"@context":"https://schema.org","@type":"Organization","name":"ShoutingNow","url":"https://shoutingnow.com/","logo":{"@type":"ImageObject","url":"https://shoutingnow.com/wp-content/themes/shoutingnow-theme/assets/images/logo.png"},"sameAs":["https://x.com/makani20","https://www.linkedin.com/in/makani20/","https://post-see.com"],"contactPoint":{"@type":"ContactPoint","contactType":"customer support","email":"support@shoutingnow.com","url":"https://shoutingnow.com/contact/"},"slogan":"Learn.
