Zodiac date checker widget

A visitor picks their birthday and the widget says whether a fixed zodiac date table can actually settle their Sun sign.

What does the zodiac date checker actually check?

A visitor picks their birthday and the widget says whether that date is one of the 18 on which the Sun sign depends on the birth year. It is built on a 106-year solar census rather than a printed date range. It is free and needs no account.

Clear answers

Frequently asked questions

What does the zodiac date checker actually check?
It checks a birthday against the 18 calendar dates on which the Sun’s sign at noon changes across a 106-year census. On those dates a printed date range cannot settle the sign on its own, because the moment the Sun changes sign drifts from year to year.
How do I add it to my site?
Copy the HTML from this page and paste it into any HTML block. The widget runs entirely inside its frame and needs nothing else from your page.
Where do the 18 dates come from?
From a published study that joins 85 million U.S. births in 1994–2014 to a year-by-year solar census for 1930–2035. The full method and the dataset are available to download.
