How it works

  1. 1

    Enter when and where you were born

    Date, time (or a rough window), birth city and sex at birth. We apply the right time-zone rules for that place and year.

  2. 2

    Meet your core chart

    Your chart’s centre of gravity, shown as one of ten core essences — with the classical terms one tap away.

  3. 3

    Get your daily season

    A short morning reading on what to lean into and what to go easy on, read from your chart and the day’s energy.

Meet the archetypes

Ten core essences. Everyone has one at the centre of their chart.

Same chart, two ways to read it.

Every chart on Sky & Season has two readings of the same calculation: the Inner Constellation tells it as a story, in plain words; Classic shows the traditional chart underneath. Try it on a sample.

Sample · Mei’s chart

Core essence

The Boundless Tide

Extroverted curiosity and restless freedom — visionary and adaptable, wary of stagnation.

Mei tends to move around obstacles rather than through them, carries a lot beneath a calm surface, and recovers fast. That is how the Inner Constellation reads her chart: no terms to learn.

Mei is fictional. Nothing here is a real person’s chart.

Today’s season for The Resilient Weaver

A quiet-building day. Finish what is half-done.

Lean into
Follow-ups, tidying loose ends, one honest conversation.
Go easy on
Launching anything new, spending on impulse.

Why: the day’s energy meets your chart as The Steward — it tends to reward patience and completion more than bold starts.
