Put an Umbriel calculator on your site

Three small widgets, free to use, with no key and no sign-up. Copy the snippet and paste it into your page. They compute in the visitor’s own browser, no birth data reaches us, because there is no request for it to travel in.

Today’s Moon

The phase, the sign and how lit it is: recalculated every time the page loads.

Moon sign from a birth date

And an honest answer when the Moon changed sign that day: it names both signs rather than guessing.

The rules, such as they are

• Free, including commerciallyUse them on a personal blog or a business site. No attribution needed beyond the link already in the widget.
• Please leave the linkIt is the only thing we get out of this, and it is how a reader finds their whole chart afterwards.
• They are meant to stay putThese URLs are stable. If one ever has to move, the old one will redirect, not break your page.
• No data reaches usA birth date typed into the Moon sign widget is used in the visitor’s browser and then forgotten. We could not read it if we wanted to.
