How it works

Sharing your big three: the card of your Sun, Moon and Rising sign

Your big three are the three keys of your birth chart: the sign of the Sun, the sign of the Moon and the Rising sign. Under these three keys, the “Share my big three” button opens your phone’s share sheet with a card as an image: your three signs, your first name if you gave it, and nothing about your birth.

The big three, in three sentences

The Sun says what you are heading towards: your direction, what gives you momentum. The Moon says what you need to feel well: your inner life, your reflexes. The Rising sign says how you meet the world, and the first impression you leave. Three signs, often different, which explain why two people born under the same Sun sign can be so unlike each other.

It is the simplest way into a chart, and the question friends ask each other most: “so what are you?”. The page on how to read your birth chart goes further; the pages of the signs describe each of the twelve.

What the card shows, and what it does not

The card is a portrait image, readable in a story as well as in a message. It carries your three signs and their symbols, your first name if it is in your chart, and the address of the site.

  • It shows: the sign of your Sun, the sign of your Moon, your Rising sign, your first name.
  • It does not show: your date, time or place of birth. None of these is in the image.
  • The link that goes along leads to the chart calculator, so that the person who receives it can find their own. It never leads to your own chart page, whose address carries your birth details.

To show someone your whole chart, wheel and positions included, use the sharing of the page instead, explained in sharing a reading: that link does contain your birth details, and you know it when you send it.

Sharing, step by step

The button appears under the three keys, at the top of your chart page, when that chart was calculated on your device. On a chart received through a link, it does not appear: that big three is not yours.

  1. Open your chart page, or calculate it if you have not done so yet.
  2. Tap “Share my big three”, under the Sun, the Moon and the Rising sign.
  3. Choose where to send it in your phone’s share sheet: a story, a message, a chat.
  4. On a computer, the card is saved to your downloads and the text and its link are copied: paste them wherever you like.

Without a birth time

The Rising sign is calculated from the time and place of birth. Without a time, the card shows the Sun and the Moon only: a pair, and it remains correct.

One special case: the day when the Moon, or more rarely the Sun, changes sign. Without a time, the site cannot tell which side your birth falls on, and the card is not offered: better to share nothing than a doubtful sign. The birth time page explains what a chart becomes without it, and finding your exact birth time says where to look.

Reading a big three someone sends you

When you receive someone’s card, read it in this order: the Rising sign first, which is what you see of the person at first contact; the Sun next, what they are trying to become; the Moon last, what reassures them when they come home. Two big threes that share a sign, even in different places, often understand each other quickly.

Each sign of the big three has its page on the site: the Sun, the Moon and the Rising sign in each of the twelve signs. From your chart page, a tap on one of the three keys opens the page of your own position; the chart wheel shows where they sit in the sky of your birth.

And the person who receives it?

The link sent along the card opens the chart calculator on My Birth Chart. Within seconds, the person gets their own big three, their wheel and a first reading, free and without an account. They can then send you their card, and you compare.

If the comparison interests you beyond the three signs, the compatibility reads both of your charts in full; and if you do not know their birth details, the page on inviting your partner explains how to ask them to enter their own.

The “Share my big three” button is at the top of your chart page, under the Sun, the Moon and the Rising sign.

Frequently asked questions

Does the card contain my date of birth?

No. The card carries only your three signs, your first name if it is in your chart, and the address of the site. Neither your date, nor your time, nor your place of birth is in the image or in the link that goes along.

Where does the link shared with the card lead?

To the chart calculator, so that the person who receives the card can find their own. It never leads to your own chart page: its address contains your birth details, and the card is made to travel without them.

Why does my card only have two signs?

Because your chart was calculated without a birth time. The Rising sign depends on the time and the place: without a time, the site does not make it up, and the card shows your Sun and your Moon.

Why does the button not appear?

The button appears for a chart calculated on your device. It does not appear on a chart received through a link, nor for a birth without a time on the day the Moon or the Sun changes sign, because the sign would not be certain.

Can I remove my first name from the card?

Yes: the card takes the first name from your chart. Calculate your chart without a first name, and the card is simply titled “My big three”.
