About Us

For as long as people have roamed the Earth, they have looked up at the stars and planets in awe and wonder. It is through the motion of the point of lights in our sky that the ancients created mythology and found meaning in their world. Those teachings and knowledge have trickled down to our modern day, ebbing and flowing like the moon through time. Today, many of us turn to astrology for wisdom, self discovery, deeper meaning, and spiritual enrichment in navigating our lives. It is our mission to provide astrological tools and perspectives in service of greater self-awareness and collective wisdom in our evolving world.

AstroGraph’s TimePassages™ Software was founded in 1995 by astrologer, author, and software engineer Henry Seltzer. Through the years, as our company has grown and evolved, we remain dedicated to quality in astrological information, software development, and devotion in serving the astrological community. We care about the well-being of our planet and donate a portion of our profits each month to the environmental organizations Natural Resources Defense Council (NRDC), Change.org, and Nature Conservancy.

Our flagship products, the TimePassages™ Apps for Desktop and Mobile, are designed to be accessible to a wide range of skill levels. For students beginning their study of astrology, the apps include detailed interpretations to aid in learning. These programs are also powerful tools for advanced practitioners, offering the accuracy and feature set required for serving clients, conducting astrological research, and producing reports.

Professional astrologers like Alan Oken, Rob Brezsny, and Susan Miller all recommend the TimePassages software. The mobile app has been featured in Refinery29, AstrologyHub, The DailyDot, AppsToFollow.com, and more. The AstroGraph.com website also brings you powerful ways to explore astrology with weekly blog articles, monthly horoscopes, and a learning section. We also offer in-depth, personalized Astrology Reports and the Online Membership to make astrology available in a variety of avenues.

Meet the Team

Henry Seltzer (he/him) has a graduate degree in Linguistics, has studied Computer Science, and attended MIT as an undergraduate. But his real study has become Astrology and Tarot. Henry's journey with Astrology began with an interest in Jungian psychological symbolism in 1975. He is a seasoned astrologer, author, and sought-after speaker, but he created the popular astrology software TimePassages and wrote its acclaimed interpretations. He's considered one of the foremost authorities on planets at the edges of our solar system beyond Pluto. He is the leading expert on the planetary archetype, Eris, and you can find his book on that here. Henry is currently researching and writing another book on the astrological significance of trans-Neptunian objects, Haumea and Makemake.
