Why we're building AuraTech, and what's live so far

We started AuraTech with a simple idea: small, free, well-made tools that answer one question quickly, without sign-ups, clutter, or guesswork about what your data is being used for. No accounts, no upsells — just a clear answer in a few seconds.

Every calculator on this site runs entirely in your browser. Nothing you type — birthdays, names, anything — is ever sent to or stored on our servers. That's not a marketing line; it's just how the site is built.

What's live right now

We've started with two tools, and we're adding more over time.

Age Calculator

Find your exact age in years, months, and days, check how old you'll be (or were) on any specific date, and see how many days are left until your next birthday. Don't remember the exact day someone was born? You can enter just a year, or a year and month, and get a sensible age range instead of a fake-precise number.

Chinese Zodiac Calculator

Enter a birthday to find your Chinese zodiac sign — Rat, Ox, Tiger, Rabbit, Dragon, Snake, Horse, Goat, Monkey, Rooster, Dog, or Pig. We built this one carefully: instead of using the more commonly cited Lunar New Year date as the yearly boundary, it follows the Start of Spring (立春) convention used in Chinese astrology (BaZi). For the small number of people born in the weeks between the two dates, that distinction actually changes the answer — so we wanted to get it right rather than just close enough.

Fun ways to use these with friends

A few ideas, if you want to make it social instead of just looking up a number alone:

• Pull up the Zodiac Calculator in a group chat and have everyone share their sign before revealing it — see who guesses right.
• Use the Age Calculator's "specific date" mode to settle friendly debates, like exactly how much older one sibling is than another, down to the day.
• Save your zodiac result as an image and send it to a friend born in a different year — compare your animal signs and see how the traits stack up.
• If your birthday falls right around February — early in the year — try the Zodiac Calculator and see whether you're on the boundary between two signs. It happens more often than people expect.

What's next

We're working through a list of new tools and will share updates here as they go live. If there's something specific you'd find useful, we'd genuinely like to hear about it.
