One birth date, a whole profile

Every birthday carries a small bundle of traditions. There is the zodiac sign fixed by the sun's position, the birthstone tied to the month, and the birth flower with its own quiet Victorian meaning. Birthdex gathers all of them in one place so you can see the full picture at a glance, then save a card to share.

Pick a date above and the profile updates instantly. Nothing is sent anywhere. The zodiac dates, birthstones and birth flowers all come from static reference data built into the page, so it works offline and loads in a blink. If you want the detail behind any part of the profile, follow the links to the full month and sign pages.

How Birthdex works out your profile

  1. Your Western zodiac sign comes from the tropical date ranges (the common Aries-to-Pisces calendar most people mean by star sign).
  2. Your birthstone is the modern stone traditionally assigned to your birth month.
  3. Your birth flower is the month's traditional bloom, with its historical meaning.
  4. The day of the week is calculated for the reference year so you get a real, checkable fact.

Frequently asked questions

What is my zodiac sign?

Your zodiac sign is decided by your birth date. Enter your month and day in the tool above and you will see your Western zodiac sign together with its element, ruling planet and date range. If your birthday sits on a cusp between two signs, the tool shows the sign for the exact date.

What is a birthstone?

A birthstone is a gem traditionally tied to the month you were born, each with its own colour and meaning. December's is turquoise, June's is pearl, and every month has at least one. See the full birthstone chart for all twelve.

What is a birth flower?

A birth flower is the bloom linked to your birth month. June's is the rose, October's is the marigold, and each carries a Victorian meaning. Browse them on the birth flowers by month page.
