↗ Calculate rising sign

The sign rising on the eastern horizon at the moment of your birth. The exact time and place are essential.

Enter at least 3 characters and choose a city from the list. Check the state or region and country.

You still need to enter the UTC offset for your birth date, including daylight saving time. Photon provides the city's location, but not its historical time zone.

How does it work?

We use local sidereal time and the obliquity of the ecliptic to estimate the tropical ascendant. The calculation is approximate and supports latitudes between −66° and 66°. A few minutes can change the sign near a transition.

♡ Zodiac compatibility

Explore the elements, rhythms and symbolic relationship between two Sun signs. In advanced mode, include the rising signs too.

A symbolic reading based on whole signs, without percentages. It does not calculate aspects by degree or replace a full synastry reading, which considers the entire birth chart.

☾ Today's Moon

Estimated using the average synodic cycle of 29.53 days, without precise ephemerides.

Calculations take place in your browser. When you search for a city, only the search text is sent to Photon; your birth date and time are not sent.

Astrology is a symbolic practice for self-discovery, without scientific validation for predicting personality or events.
