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.

Is Mercury retrograde?

The question everyone asks, answered live, with the date it next turns.

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 rather than 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.
