What True Zodiac is
True Zodiac shows which IAU constellation the Sun was in on a given date, computed from the official constellation boundaries. It is provided for interest and education. It is not astrological advice, and nothing here should be relied on for any decision.
Accuracy
The calculations use published astronomical methods and data and are tested against independent sources, but they are provided as they are, without warranty of any kind. Positions near a constellation boundary, or for dates far in the past or future, carry more uncertainty.
Your results and shared links
You may share, print and post the results and images this site produces for personal, non-commercial use. The poster preview shown before you buy is watermarked and is not the poster itself. Shared links reproduce the details you entered; take care whom you send them to.
Posters
The poster is a keepsake set of digital files, drawn from the details you entered at the time of purchase: an A3 print-ready PDF, an A4 PDF, a phone wallpaper and a desktop wallpaper. Each purchase is for one set, for one birthday and name, and its download link keeps working. The files are for your own personal use, including printing and giving as a gift.
On the website, posters are sold through Lemon Squeezy, who act as the merchant of record: they take the payment, handle any tax, and send the receipt. The file is delivered from the link on this site and in your receipt email. Because it is made to order and delivered at once, it is not refundable after download, except where the law gives you that right or the file is defective, in which case contact us at support@truezodiac.co.uk and we will put it right.
In the iOS app, posters are an in-app purchase sold by Apple, and Apple's standard licence for apps applies to the app. Apple handles payment and refunds, which you can ask for at reportaproblem.apple.com. If the file itself is wrong or will not open, contact us and we will put it right.
