Your forecast: today's sky on your own birth chart

A forecast in astrology is a comparison between where the planets are now and where they were when you were born. Those contacts are transits, and they are what astrologers actually read when someone asks what is going on. Give a birth date, a time and a place, choose a day, and this calculates the transits to that chart for it.

Cast the chart

This is not a sun-sign horoscope, and the difference is the whole point. A sun-sign column is written for a twelfth of the world at once; a transit report is calculated for one chart, so the Saturn that is squaring your Sun this month is squaring yours and not everybody's. Two people born a week apart get different reports here, and people born the same day in different places get different houses.

Read the slow planets for the shape of a period and the fast ones for the day. Saturn, Uranus, Neptune and Pluto move slowly enough to sit on a point of your chart for months, and what they describe arrives gradually and stays; Mercury, Venus and Mars pass in days; the Moon passes in hours. A report that treats all of them alike will make an afternoon sound like a turning point.

What is being touched matters as much as what is doing the touching. A transit to your Sun is about direction and vitality, to your Moon about how you feel and what you need, to your Ascendant about how you meet the world. Transits to the angles of a chart are the ones people tend to notice in their lives rather than only on paper.

The house a transiting planet is passing through is the area of life it is working on — money and resources in the second, home in the fourth, work and health in the sixth, and so on. That is the half of a forecast that says where something is happening rather than what it feels like, and it needs a birth time to exist at all.

So: with a known birth time you get the whole report, houses and angles included. Without one, the chart is cast for noon, the Moon can be several degrees out and the houses are withheld rather than guessed — you still get the transits to your planets, which is most of what a forecast is.

A transit describes what a period asks of you. It does not predict events, and nothing in this report is a verdict about health, money or anybody's lifespan. Astrology at its most useful tells you what you are dealing with; what you do about it is not in the chart.

Questions people ask

What is an astrology forecast based on?

Transits: the aspects today's planets make to the planets and angles of your birth chart. It is calculated from your own chart rather than from your sun sign.

How is this different from my daily horoscope?

A daily horoscope is written for everyone born under one sign — a twelfth of the world. This is computed for one birth date, time and place, so what it shows is touching your chart specifically.

Can I get a forecast for a date in the past or the future?

Yes. Today is the default and any other day is one control away, which is the usual way to look back at something that already happened or ahead at something being planned.

Do I need my exact birth time?

Not for the transits to your planets. For the houses, the Ascendant and an exact Moon, yes — without a time the chart is cast for noon and this report leaves the houses out rather than printing ones it cannot stand behind.

Which transits should I pay attention to?

The tightest, and the slow ones. An aspect within a degree of exact is the loudest thing in the day, and a slow planet making it is describing months rather than an afternoon.
